Nanoporous gold supported cobalt oxide microelectrodes as high-performance electrochemical biosensors

Metal oxides are proposed as replacements for expensive enzymes in electrochemical biosensors, but their wide use is currently limited by poor electronic conductivity. Lang et al. engineer the nanoarchitecture of electrodes to reduce contact resistances, which leads to an ultrahigh sensitivity to glucose.

Lamella-heterostructured nanoporous bimetallic iron-cobalt alloy/oxyhydroxide and cerium oxynitride electrodes as stable catalysts for oxygen evolution

Developing stable catalysts for industrial-scale current densities is challenging. Here, the authors report self-supported laminate electrodes composed of nanoporous bimetallic iron-cobalt alloy/oxyhydroxide and cerium oxynitride hybrid that can catalyze the oxygen evolution reaction at high current densities.

Achieving volatile potassium promoted ammonia synthesis via mechanochemistry

Potassium oxide is used as a promotor in industrial ammonia synthesis, although metallic potassium is better in theory. Here, the authors demonstrate metallic potassium, an unstable metal that easily volatilizes at high temperature, can be used as a promotor for ammonia synthesis.

Spontaneously separated intermetallic Co₃Mo from nanoporous copper as versatile electrocatalysts for highly efficient water splitting

Electrochemical water splitting is an attractive energy conversion technology, but it usually suffers from low efficiency. Here, the authors report intermetallic Co₃Mo integrated on porous Cu as highly efficient electrocatalysts for alkaline HER/OER due to in-situ hydroxylation and electro-oxidation.

Extraordinary pseudocapacitive energy storage triggered by phase transformation in hierarchical vanadium oxides

Pseudocapacitive materials could enable high-performance electrochemical supercapacitors, but their practical capacitance and power density remain low. Here the authors show that in situ phase transformation triggers extraordinary pseudocapacitive energy storage in metallic isomeric vanadium oxides.

Dual-phase nanostructuring of layered metal oxides for high-performance aqueous rechargeable potassium ion microbatteries

Aqueous rechargeable microbatteries could enable new microelectronics, but their current electrode materials still suffer from low capacity and poor rate capability. Here the authors show that layered K_xV₂O₅·nH₂O with an amorphous/crystalline dual-phase nanostructure can address these issues.
