    Green ceramic hollow fiber membranes with superhydrophobic and superoleophilic surfaces (ss-CHFM/WSBA) were successfully fabricated via facile sol–gel process using tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) as precursors. In this work, silica solution was prepared using the modified Stöber method. This process was followed by dipping the pristine membranes into the sol–gel solution at various grafting times (0–90 min), grafting cycles (0–4 cycles), and calcination temperatures (400–600 °C). The wettability, surface morphology, and chemical composition of the pristine and ss-CHFM/WSBA membranes were investigated. The results showed that increasing the grafting time has increased the wettability of ss-CHFM/WSBA with high contact angle of up to 163.9°. Similarly, increasing grafting cycle has enhanced the hydrophobicity of ss-CHFM/WSBA due to the formation of hierarchical structure of grafting cycle which were more than one. The optimum calcination temperature for ss-CHFM/WSBA was identified. It was found that increasing the calcination temperature has degraded the sol template on the surface of ss-CHFM/WSBA, hence decreasing the wettability. The preliminary performance tests showed that ss-CHFM/WSBA grafted at 60 min, 3 cycles, and calcined at 400 °C showed excellent oil/water separation efficiency of 99.9% and oil flux of 137.2 L/m2h.

    This study investigate the performance and physical properties of polymer mixed membrane integrated with the microflower of titanium dioxide (TiO₂) that synthesized at different temperature value. Microflower TiO₂ has been prepared by hydrothermal method with variation of synthesized temperature at 120 °C, 150 °C and 180 °C and the polymer flat sheet membranes were fabricated via phase inversion technique. In this present work, TiO₂was used as photocatalytic, antifouling and hydrophilicity improvement. Synthesized microflower TiO₂v ia hydrothermal method offer higher surface area that able to speed up any chemical reaction of TiO₂. Prior to the fabrication of polymer mixed matric membrane, the characterization of TiO₂ have been conducted to determine the optimum synthesize temperature. Then this was followed by the measurement of properties and performance of the polymer mixed matric membrane. Further observation on the self-cleaning test at different concentration of TiO₂ wt (%) of the membranes were conducted. The results obtained showed that membrane at temperature of 150 °C with 2.5% of TiO₂ wt (%) shows a better result than others with the highest rejection rate of 99.43% that probably due to small finger like structure. Meanwhile for self- cleaning test, membrane with synthesized temperature of 150 °C showed a better result than others with the highest of retention rate before and after being exposed to UV light which were 99.42% and 98.66% respectively. Humic acid flux recovery ratio (FRR) showed a better performance for membrane at synthesized temperature of 120°C that may relate to the effect of higher surface area that TiO₂ that able to attract more water. As conclusion, PSf/TiO₂ membrane at synthesized temperature of 150 °C with 2.5% of TiO₂ wt (%) shows an excellent result that possessed a strong hydrophilic property by lowering the fouling effect and give higher retention value.

    Recently, the improvement and advancement in synthesizing nanoparticles via eco-friendly technique have been intensively explored since the used conventional physical and chemical methods always associated to the intensive energy usage and toxic waste pollution Therefore, nanoparticles synthesized from green route technique has initiate an interest among researchers due to its clean and eco-friendliness approach. In this study, the Fe doped TiOâ‚‚ were synthesized using lawsonia inermis aqueous leaf extracts that act as reducing agent as well as capping and stabilizing agent. The green synthesized powder was then calcined and characterized using XRD, FESEM, EDX, FTIR and UV-Vis while photocatalytic activity was evaluated based on photodegradation efficiency of methylene blue (MB). The new obtained green calcined powder was found to have a crystalline phase (anatase structure) with crystallite size, 6.79 nm identified by XRD. The FESEM test shows the average particle size of the green synthesized calcined Fe doped TiOâ‚‚ is in the range of 54.5 nm with capping agent (phyto-constituents) authorized by FTIR spectra. From EDX analysis, Fe ions was successfully incorporated into TiOâ‚‚ compound during synthesis process confirmed by the presence of Fe element. It was observed that the band gap energy for green calcined Fe doped TiOâ‚‚ is approximately 2.66 eV. The green synthesized calcined Fe doped TiOâ‚‚ sample presented the highest photocatalytic activity efficiency under uv light irradiation for 3 hour which is 92.2% with only 7.8% of MB remained, this value is slightly higher than that of commercial P25 powder which is 90.7%. In conclusion, the green synthesis technique of using lawsonia inermis as natural resources as reduction agent was able to produce nanoparticles Fe doped TiOâ‚‚. Moreover, the properties of Fe doped TiOâ‚‚ nanoparticles has strong potential to be used as a photocatalyst since this sustainable green synthesis technique able to produce better nanoparticles properties as compared to conventional synthesis.

    Abstract: It has been found that the preparation of green silica based on agricultural crops preserves environmental sustainability. In this study, rice husk silica (RHS) ash was prepared by burning rice husk (RH) at different temperatures (400 and 1200 Â°C). Both types of green RHS ash additives were blended with polysulfone dope, after which membranes were fabricated via phase inversion. The RHS ash that was synthesised at 400 Â°C (RHS400) had an amorphous structure with strong hydrophilic properties, while the composite membrane containing 3 wt% of RHS400 (A3 membrane) achieved the optimum properties of a dense top, an extended sub-layer of continuous smaller finger-like pores and a bottom layer of macrovoids. A satisfactory mean surface roughness, average pore size (1.90 ± 9.50 × 10−2 µm), porosity (40.66 ± 2.03%) and tensile strength (3.27 ± 0.16 MPa) were also obtained. The contact angle (52.5° ± 3.6°) further proved that this membrane was hydrophilic. The elemental and thermal analyses confirmed the presence of Si and O, which correlated with the 12% residual that was contributed by the silica inside the membrane. The optimum properties of the A3 membrane were an increased PWF (154.04 ± 7.70 L m−2 h−1) with the highest rejection of HA (96.00 ± 4.80%) and a fouling mitigation with the lowest internal resistance (6.79 ± 0.34 × 1012 m−1).

    Industrial textile wastewater is toxic due to the presence of recalcitrant color pigments and poisonous heavy metals. In this study, the hydroxyapatite (HAp)-based bio-ceramic hollow fiber membranes (h-bio-CHFM) were developed via the combined phase inversion and sintering technique. It was found that the properties of the developed h-bio-CHFMs were greatly affected by the HAp content of the ceramic suspension, and sintering temperature. The h-bio-CHFM with the sintering temperature of 1200 °C exhibited the long rod-shaped HAp particles and the smallest pore size (0.013 μm). High removals of color (99.9%), COD (80.1%), turbidity (99.4%) and conductivity (30.1%) were achieved using the h-bio-CHFM sintered at 1200 °C with stable high flux of 88.3 L/m2h. Remarkably, the h-bio-CHFM sintered in the temperature range of 1000–1200 °C also demonstrated excellent adsorption ability towards heavy metals with 100% removals. The results of this study show the potential of the h-bio-CHFM for the efficient industrial textile wastewater treatment applications.
