Summary: Graphdiyne (GDY) is an emerging 2D carbon material with unique structures and properties, making it attractive for growing heterogeneous materials for efficient energy utilization. A controllable synthesis method of ultrathin charge-transfer complexes (CTs) of nickel with terephthalic acid nanosheets on GDY has been reported, showing record-high oxygen evolution reaction (OER) activity. Experimental characterization confirms that GDY plays a key role in modulating morphological and electronic structures to accelerate the OER rate. These findings are expected to contribute to the design of more efficient catalysts for efficient hydrogen energy technologies.

Summary: An ultrathin VOx-doped NiFe alloy layer was electrodeposited on NiCoP supported by TM to achieve a highly active and low-cost bifunctional electrocatalyst for overall water splitting. The VOx@NiFe/NiCoP/TM electrode exhibits superior electrocatalytic activity for water electrolysis and shows robustness and outstanding durability in alkaline medium. Serving as both anode and cathode electrocatalysts in a two-electrode water electrolytic cell, the bifunctional electrodes only require low potentials with excellent durability.

Summary: Amorphous CoNiS nanosheets are synthesized on nickel foam (NF) through a facile structure evolution strategy and demonstrate advanced performance in water splitting at high current densities. This is attributed to the sufficient active sites exposed by the flexible amorphous configuration. The hydrophilicity and aerophobicity of a-CoNiS/NF promote surface wettability and avoid bubble aggregation, facilitating mass transfer and achieving low overpotentials for hydrogen and oxygen evolution reactions under alkaline conditions.

Summary: Electrochemical CO2 reduction reaction (CO2RR) is a significant process for recycling excessive CO2 in the atmosphere. However, the discovery of efficient catalysts for CO2RR is currently lagging behind due to limitations in current methods. To overcome this, researchers have increasingly used modern machine learning (ML) algorithms to accelerate catalyst screening and deepen our understanding of the mechanism. In this review, we examine recent applications of ML in CO2RR research, categorizing them by the types of electrocatalysts, and provide an introduction to the general methodology as well as a discussion on the pros and cons of such applications.

Summary: This paper proposes an analysis theory of low carbon route choice behavior based on improved prospect theory by analyzing the punctuality rate of travel time and the travelers' comfort level. The optimization model of travelers' intermodal transport under bounded rationality is constructed by setting dual reference points according to the whether travelers have prior experience. The results show that the travel route selected by travelers in consideration of carbon emissions will change with the road state, and the sensitivity coefficients of gain and loss have an impact on the decision.
