Coating disk-shaped materials on the bottoms of vessels: a convenient while marvelous practice for tribocatalysis

Abstract

Tribocatalysis has emerged as a promising catalytic technology to utilize mechanical energy through friction to many important applications in recent years. Numerous studies have shown that introducing materials from outside to form dynamic friction with tribocatalysts is an effective method to enhance tribocatalysis, and many disk-shaped materials have been introduced to take part in tribocatalysis through being coated on the bottoms of beakers and reactors. Up to date, these disk-shaped materials termed as coatings in the literature encompass four distinct types of materials, namely polymers, metals, ceramics, and semiconductors. This paper reviews their effects on the tribocatalytic degradation of organic dyes and the tribocatalytic production of flammable gases from H₂O and CO₂, and discusses their implications for future researches on coatings in tribocatalysis. Due to the highly marvelous effects already observed for these coatings that have been investigated, it is hoped that this paper will promote coating disk-shaped materials on the bottom of vessels to be adopted as a general practice for tribocatalysis.
