Both Cu-containing enzymes (3, 4) and zeolites (6, 10, 11) convert CH 4 into CH 3 OH.The oxidation state of the copper in these systems is usually assumed to be +2 before reaction with CH 4 and +1 after CH 4 activation ().In AP-XPS experiments, we found a very low reactivity of plain Cu 2 O/Cu(111) systems toward CH 4 at room temperature. The development of highly active and durable catalysts for electrochemical reduction of CO2 (ERC) to CH4 in aqueous media is an efficient and environmentally friendly solution to address global problems in energy and sustainability. Metal species with different size (single atoms, nanoclusters, and nanoparticles) show different catalytic behavior for various heterogeneous catalytic reactions. This special issue honors Professor James J. Morgan, who served as the founding editor-in-chief of ES&T from 1967 to 1975 and sadly passed away in 2020.

Transmission electron microscopy revealed that the strong metal-support interaction (SMSI)induced encapsulation of platinum particles on titania observed under reducing conditions is lost once the system is exposed to a Black TiO2x Nanoparticles Decorated with Ni Nanoparticles and Trace Any dielectric material under a strain gradient presents flexoelectricity. The dynamic interactions between noble metal particles and reducible metal-oxide supports can depend on redox reactions with ambient gases. Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 and 100 nm (the usual definition of nanoscale).. Nanomaterials research takes a materials science-based approach to nanotechnology, leveraging advances in materials metrology and synthesis which have been developed in support of microfabrication research.

Here, we report the stabilization of Cu+ within a CuOCeO2 interface for efficient and selective electrocatalytic CO2 reduction to ethylene under ambient conditions. These important features make them the most preferred engines especially for heavy-duty vehicles. Synthesis of N doped porous carbon materials. Owing to the maximum efficiency of atom-utilization and unique structures and properties, Single-atom alloys (SAAs) play an increasingly significant role in the field of single-site catalysis and are typically composed of catalytically active elements atomically dispersed in more inert and catalytically selective host metals. Frederic Meunier and Helena Kaper It is therefore possible that the high activity observed at low temperatures on the Pt/CeO2_S was actually due in part, if not totally, to Pt nanoparticles, as shown in earlier work on Pt/ nanosized CeO2 (ACS Catal., 2016, 6 (9), pp 61516155, DOI: 10.1021/acscatal.6b00677). It has been shown in the literature that many factors including the particle size, shape, chemical composition, metalsupport interaction, and metalreactant/solvent interaction can have significant MOF-derived cobalt nanoparticles catalyze a general synthesis of amines.
