Journal of CO2 Utilization, Vol 85, Iss , Pp 102887- (2024)
Catalysis has optimized and improved production rates in many industrial processes. Conventional catalysis plays a key role in the mass-production of otherwise difficult to obtain substances. Plasma catalysis, plasma incorporation to appropriate cata

Abstract This work presents a hydrothermal-based facile method for synthesizing ZnFe2O4, whose size can be controlled with the concentration of sodium acetate used as a fuel and its physical changes at nanoscales when exposed to two different gases.

Replacing the conventionally used steam reforming of methane (SRM) with a process that has a smaller carbon footprint, such as dry reforming of methane (DRM), has been found to greatly improve the industry’s utilization of greenhouse gases (GHGs).
