140 results about "Proton acceptor" patented technology

A proton acceptor is another name for a base, which is the opposite of an acid. In the Broensted-Lowry definition, a base is a negatively charged ion that will react with, or accept, a positively charged hydrogen ion. Since a hydrogen ion is aproton, the base is called a proton acceptor.

Electronegative heteroatom-transition metal co-doped carbon-based non-noble metal electrocatalyst and preparation method thereof

The invention discloses an electronegative heteroatom-transition metal co-doped carbon-based non-noble metal electrocatalyst and a preparation method thereof, and belongs to the field of new energy and electrocatalytic materials. The preparation method comprises the following steps: fully stirring and reacting a carbon source, a phosphorus source, a nitrogen source, a sulfur source and transitionmetal salt in a solvent, carrying out a solvothermal reaction, carrying out high-temperature carbonization treatment in a nitrogen atmosphere, and finally, carrying out acid washing and drying treatment to obtain the electronegative heteroatom-transition metal co-doped carbon-based non-noble metal electrocatalyst. According to the catalyst, the phosphorus source, the nitrogen source and the sulfursource are introduced in situ in the molecular synthesis process to improve the metal loading capacity and dispersity effectively, the conductivity of the catalyst is greatly improved due to the existence of the carbon material, the interaction between phosphorus and a reaction intermediate is fully utilized to form surface receptor sites with proton receptors and hydrides, and high activity is caused. The preparation method of the catalyst is simple, easily available in raw materials, low in cost, easy to control in process, short in preparation period, high in yield and suitable for large-scale production.
