Special Issue Information

Dear Colleagues,

Sustainable development and a circular economy have become guiding principles for modern society, bringing a growing appreciation that anthropogenic waste can offer a valuable source of energy, chemicals, or high value functional products. A circular economy needs chemistry to provide a basis for innovative products; these are made from waste materials and designed to be reused or recycled, increasing the value of a material resource by maximising its conversion into products (high value), thus eliminating waste (low value). In the context of chemical transformations, high volume waste materials from both large-scale industrial and natural sources are attracting increasing interest in terms of catalysis. The main focus of this Special Issue is to solicit recent advances in the use of waste materials to generate electrocatalysts for energy and environmental applications, such as electrochemical reactions that take place in fuel cells, batteries, electrolyzers, or in the electrochemical reduction of CO2. These waste materials can be directly applied as electrocatalysts themselves, or they can be used as sources of components from which materials of electrocatalytic interest can be prepared.

Cost-efficient and sustainable electrocatalysts for oxygen evolution reaction (OER) is highly desired in the search for clean and renewable energy sources. In this study, we develop a new one-step synthesis strategy of novel composites based on Ni and molybdenum carbide embedded in N- and P-dual doped carbon matrices using mainly chitosan biopolymer as the carbon and nitrogen source, and molybdophosphoric acid (HMoP) as the P and Mo precursor. Two composites have been investigated through annealing a mixture of Ni/chitosan and HMoP with two unlike carbon matrices, melamine and graphene oxide, at a high temperature. Both composites exhibit similar multi-active sites with high electrocatalytic activity for OER in an alkaline medium, which is comparable to the IrO2 catalyst. For this study, an accurate measurement of the onset potential for O2 evolution has been used by means of a rotating ring-disk electrode (RRDE). The use of this method allows confirming a better stability in the chitosan/graphene composite. This work serves as a promising approach for the conversion of feedstock and renewable chitosan into desired OER catalysts. Full article
