Summary: This article introduces the application of functionalized MXenes in the electrochemical reduction of carbon dioxide, focusing on the catalytic performance and selectivity of MXenes with O-termination in CO2RR. The study found that O-terminated MXenes demonstrated excellent CO2RR behavior through the choice of the *HCOOH pathway, which is mainly attributed to the better coordination between reaction intermediates and binding energies of *COOH/*HCOOH. The selectivity for CO2RR is higher than hydrogen evolution reaction (HER), depending on the efficiency of the catalyst.

Summary: Exploring unique single atoms as catalytic sites is important but challenging for improving photocatalytic CO2 reduction. Gallium (Ga) single atoms decorated on CdSe quantum dots (QDs) effectively enhance the CO evolution rate to 16.1 mu mol h(-1) with a selectivity of 90.4% over 30 hours, surpassing bare CdSe QDs. The mechanism involves efficient separation of electron-hole pairs and enhanced CO2 adsorption ability due to Ga single atoms, as well as effective electron trapping and suppression of H-2 evolution by surface Ga catalytic sites.

Summary: It has been found that the thermal catalyst Cu/ZnO/Al2O3 can enhance the catalytic performance of CO2 hydrogenation for the reverse water-gas shift and methanol synthesis reactions. However, due to direct competition between these reactions, high pressure and high hydrogen concentration are required to shift the thermodynamic equilibrium towards methanol synthesis. In this study, a new black indium oxide with photothermal catalytic activity was prepared, and it enabled the tandem synthesis of methanol at a low hydrogen concentration and ambient pressure by utilizing by-product CO as feedstock. The methanol selectivities achieved 33.24% and 49.23% at low and high hydrogen concentrations, respectively.

Summary: Low-cost and high-performance electrocatalysts, particularly metal (oxy)hydroxides, have gained significant attention for their promising oxygen evolution reaction (OER) activity. Amorphous electrocatalysts exhibit superior activity and structural flexibility compared to crystalline counterparts, but traditional preparation techniques pose a barrier. In this study, amorphous NiFe (oxy)hydroxides on nickel foam with a large surface area and small charge transfer resistance were fabricated using an electrodeposition technique. The as-fabricated NiFe (oxy)hydroxides (Ni:Fe = 1:3) demonstrated remarkable electrocatalytic activity and stability for OER, outperforming noble metal electrocatalysts (RuO2) and most NiFe-based electrocatalysts with a low overpotential of 245 mV at a current density of 100 mA cm(-2) and a small Tafel slope of 76.9 mV dec(-1). This work provides a facile and effective method for synthesizing metal (oxy)hydroxide catalysts for high-efficiency water splitting.

Summary: The concept of chainmail catalyst, which encapsulates an active species within a carbon support, is well-established to ensure extraordinary stability for catalytic reactions in harsh conditions. However, conventional chainmail catalysts suffer from poor accessibility to active sites, resulting in the need for additional voltage to compensate for sluggish diffusion kinetics in electrocatalysis. In this study, cobalt nanoparticles were encapsulated within N-doped carbonized wood to create a monolithic chainmail electrocatalyst. The resulting catalyst exhibited excellent performance as an electrode for hydrogen evolution, oxygen evolution, and monosaccharide oxidation reactions.

Summary: Developing excellent electrocatalysts is crucial for the widespread application of the electrochemical hydrogen evolution reaction (HER). MoS2 is a promising alternative to platinum-based catalysts, however, its HER activity is not comparable to platinum due to the lack of active sites. In this study, a novel strategy was developed to activate the basal planes of MoS2 using a facile hydrothermal method and low-temperature H2O2 etching method. The dual defects MoS2 nanosheet exhibited remarkable HER activity, achieving 10 mA cm(-2) with a small overpotential of around 143 mV in 0.5 M H2SO4.
