Using commercially activated carbon, we developed a simple and effective direct chemical oxidation route to prepare good biocompatible multicolor photoluminescent carbon dots.
Metallic zinc (Zn) is one of the most attractive multivalent-metal anode materials in post-lithium batteries because its high abundance, low cost and theoretical capacity. However, it usually suffers from large voltage polarization, Coulombic efficiency propensity for dendritic failure during Zn stripping/plating, hindering practical application aqueous rechargeable zinc-metal (AR-ZMBs). Here we demonstrate that anionic surfactant-assisted situ surface alloying Cu remarkably improves...
Developing robust nonprecious-metal electrocatalysts with high activity towards sluggish oxygen-evolution reaction is paramount for large-scale hydrogen production via electrochemical water splitting. Here we report that self-supported laminate composite electrodes composed of alternating nanoporous bimetallic iron-cobalt alloy/oxyhydroxide and cerium oxynitride (FeCo/CeO2-xNx) heterolamellas hold great promise as highly efficient alkaline reaction. By virtue three-dimensional architecture...
Abstract Electrochemical nitrogen reduction reaction (NRR) for ammonia synthesis has attracted great interest in recent years, which presents a carbon‐free alternative to the energy‐intensive Haber–Bosch process. Besides, NRR also provides promising coverage route of renewable energy since NH 3 is considered second generation hydrogen while possessing established technologies liquefaction, storage, and transport. However, there are long‐term challenges catalyst design due its low intrinsic...
Abstract Aqueous zinc‐ion batteries are attractive post‐lithium battery technologies for grid‐scale energy storage because of their inherent safety, low cost and high theoretical capacity. However, practical implementation in wide‐temperature surroundings persistently confronts irregular zinc electrodeposits parasitic side reactions on metal anode, which leads to poor rechargeability, Coulombic efficiency short lifespan.

Abstract Ambient electrochemical ammonia (NH 3 ) synthesis is one promising alternative to the energy‐intensive Haber–Bosch route. However, industrial requirement for NH production with amperes current densities or gram‐level yield remains a grand challenge.

Potassium oxide (K2O) is used as a promotor in industrial ammonia synthesis, although metallic potassium (K) better theory. The reason K2O because K, which volatilizes around 400 °C, separates from the catalyst harsh synthesis conditions of Haber-Bosch process. To maximize efficiency using K with low temperature reaction below °C prerequisite. Here, we synthesize and Fe via mechanochemical process near ambient (45 1 bar). final concentration reaches high 94.5 vol%, was extraordinarily higher...
Ammonia (NH3 ) is essential for modern agriculture and industry, and, due to its high hydrogen density no carbon emission, it also expected be the next-generation of "clean" energy carrier.

Especially, catalyst CuCo2 O4 /Ni can simultaneously promote eNOx RR...
