Summary: Converting CO2 into useful resources through electrocatalysis and photocatalysis is a promising strategy for recycling the gas and electrifying industries. Research has shown that multinuclear metal catalysts outperform monometallic catalysts due to synergistic effects between metal sites. Recent progress on electrocatalytic and photocatalytic reduction of CO2 using earth-abundant bimetallic molecular catalysts is summarized in this review.

Summary: A new Yin-Yang hybrid co-catalyst has been proposed for efficient water splitting, showing higher activity compared to traditional spatially separated dual co-catalysts. The superior performance is attributed to the adjacent spatial configuration, extra use of surface excitons, and more favorable water molecular absorption.

Summary: Photocatalytic proton reduction is a promising method for producing clean and sustainable dihydrogen. Immobilizing catalysts and photosensitizers on liposomes is an attractive approach for biomimetic solar fuel production. The stability of the catalyst has been a limitation in current systems, but a new cobalt complex immobilized on the lipid bilayer of liposomes has shown improved performance in this study.

Summary: This study successfully prepared a photocatalyst by dispersing cobalt phthalocyanine (CoPc) molecules with intrinsic Co-N-4-C moiety on graphene oxide (GO) for photocatalytic CO2 reduction reaction (CO2RR). The existence of Co-O-C axial coordination bond between CoPc and GO was confirmed by systematic characterization of the morphology, structure, and component of CoPc/GO composites. The optical, photoelectric, and electrical properties of CoPc/GO composites were carefully investigated, indicating the synergistic role of CoPc and GO in photocatalysis. With the optimal CoPc/GO sample as photocatalyst, an evolution rate of 1500 μmol/g/h and a selectivity of 85% for CO and CH4 were achieved, which were much higher than those performances of CoPc.

Summary: CeO2 decorated reduced graphene oxide (CeO2@rGO) nanocomposites were synthesized and studied for their tribological, anti-corrosive, and photocatalytic applications. The nanocomposites exhibited reduced friction coefficient in the presence of lubricating oil, improved corrosion resistance in the coating, and enhanced efficiency in RhB dye removal. These effects are attributed to the unique properties and synergistic effects of the CeO2 nanoparticles and rGO in the nanocomposites.

Summary: In this study, LuFe1-xCoxO3 powders with different doping concentrations were successfully prepared by a mechanochemical activation-assisted solid-state reaction method. XRD and FTIR studies showed a contraction of lattice parameters when B-site Fe ions were substituted by Co ions. SEM and EDS were used to investigate the morphology and elemental distribution. UV-visible absorbance spectra indicated that LuFe0.85Co0.15O3 powders have a narrower bandgap and higher absorbance compared to LuFeO3, leading to improved light utilization efficiency. Additionally, LuFe0.85Co0.15O3 powders exhibited higher photocatalytic activity and could almost completely degrade MO under visible irradiation with the assistance of oxalic acid. This study is expected to promote the application of orthorhombic LuFeO3 in photocatalysis.

Summary: In this study, Co(II) citrate complex nanoparticles (CoC NPs) were synthesized and immobilized on GO sheets to form a binary nanocomposite, CoC/GO. The self-condensation reaction of citric acid facilitated the in situ construction of GO support and grafting of complex NPs onto its surface. The resulting CoC/GO nanocomposites demonstrated high catalytic activity in visible light-induced water splitting.

Summary: This study investigates the photocatalytic degradation property of europium oxide (Eu2O3) nanoparticles synthesized via chemical precipitation and calcination processes, with surface modification using surfactants such as polyvinyl pyrrolidone (PVP) and hexadecyl trimethyl ammonium bromide (CTAB). The results show that Eu2O3 nanoparticles synthesized with surfactant CTAB exhibit improved photocatalytic degradation efficiencies for degrading rhodamine B dye compared to pure Eu2O3 nanoparticles and those synthesized with PVP. The enhanced performance can be attributed to the increased bandgap of Eu2O3 and the influence of the surfactant on the luminescence of Eu3+ and carrier redistribution of energy levels.
