Summary: Ni catalysts decorated with trace Rh supported on gamma-Al2O3 were prepared and investigated for the catalytic hydrodechlorination of chlorinated hydrocarbons. The introduction of Rh facilitated the generation of spillover hydrogen, enhancing the H2 activation ability of the Ni catalyst. The bimetallic Ni-Rh/gamma-Al2O3 catalyst exhibited significantly higher 1,2-dichloroethane conversion (37%) and comparable selectivity to ethylene (95%) compared to the monometallic Ni catalyst.

Summary: Crystal engineering of metal oxide supports is a new strategy to enhance the catalytic performance of noble metal catalysts in catalytic oxidation of CVOCs. Pt catalysts on different crystal phases of TiO2 exhibited varying activity, selectivity, and stability in the oxidation of DCE, with the Pt/TiO2-P catalyst showing optimal performance. The strong interaction between Pt and P25-TiO2, as well as the presence of abundant hydroxyl groups, contributed to the stability and high activity of the Pt/TiO2-P catalyst.

Summary: In this study, we synthesized amorphous MoSx (a-MoSx) and Ag on TiO2 to improve the removal of photocatalytic organic pollutants. The TiO2/a-MoSx/Ag (TMA) photocatalyst showed significantly enhanced degradation performance of methylene blue compared to TiO2 photocatalyst. Moreover, by coating the TMA photocatalyst on an ultrafiltration (UF) membrane using polydopamine (PDA), fouling of the membrane was successfully mitigated, resulting in increased hydrophilicity and improved flux recovery ratio.

Summary: Platinum was incorporated onto titania-mesoporous carbon composite and tested for glycerol photoreforming. The high surface area of the mesoporous carbon promoted the dispersion of titania, while photodeposition led to preferential incorporation of platinum onto titania. The Pt/TiO2-MCH catalyst, with 18.4 wt% titania and 1.3 wt% platinum, showed a hydrogen production three times higher than the Pt/TiO2 catalyst after 12 hours.

Summary: Platinum was deposited on g-C3N4-TiO2 systems using UV or Vis light, and the resulting particle size and distribution were influenced by the absorption properties of the semiconductors. Smaller platinum particles were obtained on g-C3N4 under visible light and on TiO2 under UV radiation. The preferential deposition of platinum on g-C3N4 or TiO2 was observed, especially in physical mixtures of both semiconductors, depending on the radiation source. The solids showed enhanced hydrogen photoproduction activity under visible light, compared to physical mixtures or simultaneous incorporation of platinum.

Summary: Microbial EPS are an important source of labile component in natural organic matter, and their sorption behavior to mineral surfaces can significantly affect the sorption of hydrophobic organic contaminants. The type and surface properties of minerals, as well as the biological source of EPS, play key roles in sorption fractionation of EPS on minerals and ultimately impact the sorption affinity of apolar HOCs to EPS-mineral complexes.EPS-mineral complexes exhibited larger sorption coefficients than pristine EPS, indicating that sorptive interactions were facilitated by sorbed EPS on mineral surfaces.

Summary: Selective binding of aromatic compounds is achieved by introducing oxygen-containing functional groups on the surface of graphene oxide (GO). The size matching and polarity matching mechanism allows small apolar compounds to bind with the isolated aromatic region of GO, resulting in higher binding selectivity compared to larger apolar compounds. The interactions between the functional groups of polar aromatics and the epoxy/hydroxyl groups on GO enhance binding selectivity.

Summary: This study demonstrates that CO2 hydrogenation can be tuned from CH4 to CO by phosphating Ni-based catalysts due to the geometric effect. Nickel phosphide catalysts with different crystalline phases show different CO2 conversion, with Ni12P5 being more active. Confining small Ni12P5 nanoparticles in mesoporous SiO2 channels enhances the activity due to the confinement effect. The results suggest that Ni12P5@SBA-15 can achieve near-unity CO selectivity and enhanced activity for CO2 hydrogenation by combining the geometric effect and the confinement effect.
