Summary: Heteroatom incorporation is commonly utilized in photocatalysis to construct highly active centers, and cobalt is a desirable dopant for photocatalytic hydrogen production. This study successfully incorporated cobalt into ZnIn2S4 nanosheets, resulting in improved electron occupancy and water dissociation. The enhanced covalency of Co-S bonds balanced hydrogen adsorption and desorption, favoring H2 production. However, increased Co doping weakened water adsorption. Optimum cobalt doping in ZnIn2S4 achieved a significantly enhanced H2-evolution rate of 72.1 μmol h-1, 5.5 times higher than ZnIn2S4.

Summary: As nations transition towards low or net zero carbon economies due to global climate change, the need for practical alternative fuels is urgent. Hydrogen gas is considered one of the most desirable substitutes for traditional hydrocarbons, but obtaining "green" hydrogen from low or zero carbon footprint sources presents challenges. Research focuses on practical techniques for producing "green" hydrogen through photocatalytic or photoelectrocatalytic processes. However, the capability of this technology to produce hydrogen at scale has faced significant issues. This road map article explores various aspects of photocatalytic and photoelectrocatalytic hydrogen generation, including processes, materials science, reactor engineering, and biomass reforming applications.

Summary: In recent years, water scarcity has become a significant problem due to population growth, industrial progress, and climate change. Water pollution caused by hazardous pollutants like toxic metals and phenolic compounds demands urgent attention. Coal fly ash and coal bottom ash wastes have been explored as low-cost raw materials for producing suitable materials for cleaner wastewater treatment. These materials have shown promise in removing toxic metals and phenolic compounds through adsorption, membrane filtration, and photocatalysis. Future research should focus on recycling coal ashes and advancing processes for more efficient wastewater remediation.

Summary: Air pollution caused by particulate matter and ozone in Chinese megacities is a major health concern, partially due to the emissions of nitrogen oxides. Therefore, advanced methods, such as photocalysis using polymeric carbon nitride, are needed for nitrogen oxide removal. However, this process is limited by low visible-light absorption, specific surface area, carrier recombination, and conversion pathways. In this review, catalysts made of polymeric carbon nitride for the removal of nitrogen oxides are discussed, focusing on improving light absorption, increasing surface area, inhibiting carrier recombination, regulating the reaction process, outdoor applications, and reducing nitrogen oxides to dinitrogen.

Summary: Photothermocatalysis is a process that combines thermal and light energies, and ceria is a promising candidate as a photothermocatalyst for VOCs combustion. However, the impact of its exposed facets on photothermocatalytic activity is not well understood due to a lack of suitable facet control strategies. In this study, we used a MoO42- inducing method to modulate the exposed facets of CeO2 nanorods and investigated their effect on toluene combustion. Our results showed that CeO2 nanorods with the (100) and (111) facets exhibit higher thermocatalytic activity for toluene combustion compared to nanorods with only the (111) facet, and the (100) facet is more easily photo-activated, leading to a significant enhancement in activity when both thermal and light energies are involved. In situ FTIR analysis revealed the possible reaction mechanism of photothermocatalytic toluene combustion over ceria. This study provides new insights into the correlation between ceria exposed facets and photothermocatalytic activity.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
