Some embodiments are directed to a new methodology aimed at preparing highly N-doped mesoporous carbon macroscopic composites, and their use as highly efficient heterogeneous metal-free catalysts in a number of industrially relevant catalytic transformations.

Provided are a superatomic material, as well as a sol, a preparation method therefor, and application thereof. The superatomic material comprises a carrier and superatoms doped in the carrier, the superatoms being one or more of silver, copper, zinc superatoms and rare earth element superatoms, the scale of superatoms being 100-3000 pm, and the carrier being an inorganic carrier. The superatomic material and the sol have superior antimicrobial and antiviral properties, have a long service life, and are environmentally friendly.

A non-stoichiometric nanocomposite coating and method of making and using the coating. The non-stoichiometric nanocomposite coating is disposed on a base material, such as a metal or ceramic; and the nanocomposite consists essentially of a matrix of an alloy selected from the group of Cu, Ni, Pd, Pt and Re which are catalytically active for cracking of carbon bonds in oils and greases and a grain structure selected from the group of borides, carbides and nitrides.

A photocatalytic device includes a substrate having a surface, and an array of conductive projections supported by the substrate and extending outward from the surface of the substrate. Each conductive projection of the array of conductive projections has a semiconductor composition. The semiconductor composition establishes a photochemical diode. The surface may be nonplanar such that subsets of the array of conductive projections are oriented at different angles.
