Homogeneously Distributed Heterostructure Energizes and Replenishes Oxygen Species for Boosting Toluene Oxidation on Perovskite Oxide Catalysts.

Enriching oxygen species in perovskite catalysts provides more active sites for the catalytic oxidation of air pollutants, but its further application in environmental chemical engineering is still constrained by the inherent lack of oxygen species reactivity and the difficulty of replenishing depleted oxygen species. Herein, we present a scalable one-pot strategy for the in situ fabrication of a homogeneously distributed heterostructure, which brings LaCuO perovskite a 58-fold activity enhancement and robust antisintering/water/coke in toluene oxidation, higher than currently reported perovskite catalysts. Superior to the single "oxygen enrichment" effect of conventional surface-aggregated heterostructures, the homogeneously distributed heterostructures induce the reactivity enhancement of adsorbed oxygen and the backfilling/replenishment of depleted lattice oxygen, which break through the rate-determining steps of the low-temperature Langmuir-Hinshelwood and the high-temperature Mars-van Krevelen mechanisms, respectively.

Satellite-Based Estimation of Nitrous Oxide Concentration and Emission in a Large Estuary.

Estuaries are nitrous oxide (NO) emission hotspots and play an important role in the global NO budget.

This study retrieved water environmental variables associated with NO cycling based on satellite imagery and developed a machine learning model for NO concentration estimations.

All-natural charge gradient interface for sustainable seawater zinc batteries.

Paring seawater electrolyte with zinc metal electrode has emerged as one of the most sustainable alternative solutions for offshore stationary energy storages owing to the intrinsic safety, extremely low cost, and unlimited water source.

Here, we reveal that chloride pitting initiates negative electrode corrosion and aggravates dendritic deposition, causing rapid battery failure.
