Through in situ high-resolution transmission electron microscopy (TEM), the coexistence of two fusion mechanisms of Au clusters on TiO2 under ultraviolet–visible (UV–Vis) light irradiation in air is identified, i.e., the migration and coalescence (MC) and Ostwald ripening (OR). Additionally, the Au clusters have higher stability in an inert N2 atmosphere or vacuum than the oxidizing atmospheres (i.e., air and O2).

The weft-knitted reduced graphene oxide (r-GO) textile that is made up of many conductive r-GO coated fibers was successfully prepared dependent on the electrospray deposition technique. Based on the negative resistance variation characteristic in three dimensions, the r-GO textile transverse-strain and pressure sensors all show the excellent sensing characteristics.

Cobalt-embedded hollow nitrogen-doped carbon spheres with enhanced oxygen reduction reaction (ORR) activity and stability are fabricated via a metal-organic-framework-engaged self-templated strategy. The enhanced ORR performance can be attributed to the hollow structure which provided enlarged electrochemically active surface area, more active Co-N species and defects.

Two-dimensional group-11-chalcogenides (M2X, M = Cu, Ag, Au; X = S, Se, Te) adopt variable configurations due to their natural non-layer bulk phases. A group of M2X monolayers were proposed, possessing a broad range of band gaps ranging from 0.49 to 3.76 eV and high room-temperature carrier mobilities.

Cu2Sb decorated Cu nanowire arrays on Cu foil were employed as a high-performance catalyst for electrochemical CO2 to CO conversion. In CO2-saturated 0.1 M KHCO3 solution, it achieves a high Faraday efficiency (FE) of 86.5% for CO, at –0.90 V vs. reversible hydrogen electrode (RHE), and the H2/CO ratio is tunable from 0.08:1 to 5.9:1 by adjusting the potential.
