Controllable properties of NiO nanostructures fabricated by plasma assisted-chemical vapor deposition.

An original plasma assisted vapor phase route is proposed for the low-temperature fabrication of supported NiO nanostructures on conductive glasses. The sole deposition time variation enables to tailor material properties, modulating, in turn, the system wettability and functional performances in the photodegradation of recalcitrant pollutants.

Plasma-assisted fabrication of ultra-dispersed copper oxides in and on C-rich carbon nitride as functional composites for the oxygen evolution reaction.

Significant efforts have been continuously devoted to the mastering of green catalysts for the oxygen evolution reaction (OER), whose sluggish kinetics prevents a broad market penetration of water splitting as a sustainable route for large-scale hydrogen production. In this extensive scenario, carbon nitride (CN)-based systems are in focus thanks to their favorable characteristics, and, whereas graphitic CN has been largely investigated, the potential of amorphous carbon nitride (a-CN) systems remains almost entirely unexplored. In this regard, our study presents a novel two-step plasma-assisted route to a-CN systems comprising ultra-dispersed, "quasi-atomic" CuO ( = 1, 2).

Graphitic Carbon Nitride Structures on Carbon Cloth Containing Ultra- and Nano-Dispersed NiO for Photoactivated Oxygen Evolution.

The development of low-cost and high-efficiency oxygen evolution reaction (OER) photoelectrocatalysts is a key requirement for H generation via solar-assisted water splitting. In this study, we report on an amenable fabrication route to carbon cloth-supported graphitic carbon nitride (gCN) nanoarchitectures, featuring a modular dispersion of NiO as co-catalyst. The synergistic interaction between gCN and NiO, along with the tailoring of their size and spatial distribution, yield very attractive OER performances and durability in freshwater splitting, of great significance for practical end-uses.
