Summary: The future focus should be on developing sustainable cities through reducing energy waste and constructing carbon-neutral environments. This requires the development of smart homes with self-sufficient power generation, storage, and consumption systems based on distributed renewable energy resources and good infrastructure. However, no alternative energy source can fully meet these demands, even though wind and solar energy are often the most practical forms of renewable energy. Current research is focused on combining these two energy sources to take advantage of their complementary characteristics. The deployment of optimal renewable energy systems in each house is challenging due to various socio-economic barriers, leading to decision-making problems. The proposed hybrid fuzzy decision-making technique shows promise for making forward-thinking judgments on real-world challenges, given its outcome sustainability, accuracy, and consistency.

The optimized amorphous black phosphorus/zinc phosphate composite anode retains a capacity of 369.0 mA h g-1 and reduces the volume expansion to 47% compared to the untreated electrode. Additionally, the amorphous zinc phosphate can absorb water, resulting in good environmental stability even after exposure to humid air for two days, with a reversible capacity of 629.2 mA h g-1.

Summary: Electrochemical nitrate reduction reaction (NO3RR) has potential in wastewater management and carbon-neutral ammonia synthesis, but lacks high-quality catalysts with controllable reaction pathways and high activity and selectivity. In this study, we explore the application of single atom alloys (SAAs) in nitrate reduction through high-throughput first-principles calculations. We identify Ni/Cu(111) as the most active SAA catalyst for NO3RR and find that the adsorption free energy of *NO3 can serve as an efficient descriptor to design and predict the NO3RR performance of SAAs. Furthermore, we reveal the pH-dependent properties of Cu-based SAAs, which influence the competition between the hydrogen evolution reaction (HER) and NO3RR.

Summary: A carbothermal reduction approach and stable electrode/electrolyte interface construction regulated by voltage are used to ensure the ultra-long cycling performance of potassium ion batteries (PIBs) with pure-phase KVOPO4 materials. The KVOPO4 materials demonstrate a stable 3D crystal framework and efficient K+ diffusion, leading to high reversibility and low-capacity decay upon cycling. The exceptional structure and robust electrode/electrolyte interface of KVOPO4 materials explain their cycling stability.

Summary: The synergistic regulation of electronic structures of transition-metal oxide-based catalysts using oxygen vacancy defects and single atom doping can significantly enhance their performance in oxygen evolution reaction (OER). In this study, a simple defect-induced in situ single-atom deposition strategy was developed to deposit atomically dispersed Ru single atoms onto oxygen vacancy-rich cobalt oxides (Ru/Co3O4-x) by a spontaneous redox reaction. The resulting Ru/Co3O4-x electrocatalyst, with the coexistence of oxygen vacancies and Ru atoms, exhibited excellent OER performance with a low overpotential, small Tafel slope value, and good long-term stability in alkaline media. Density functional theory calculations revealed that the synergy between oxygen vacancies and atomically dispersed Ru can optimize the adsorption of oxygen-based intermediates and reduce the reaction barriers of OER by tailoring the electron decentralization and d-band center of Co atoms. This study proposes a feasible strategy for constructing electrocatalysts with abundant oxygen vacancies and atomically dispersed noble metals, and provides a deep understanding of the electronic engineering of transition-metal-based catalysts to boost OER.
