Patent ID: 11857952

Abstract:
The present disclosure belongs to the technical field of electrocatalytic materials, and provides a graphitic carbon-doped and mixed crystal-type titanium dioxide nanotube composite for electrocatalysis, and a preparation method and use thereof. The composite for electrocatalysis includes a titanium substrate and a titanium dioxide nanomesh deposited on the titanium substrate, where the titanium dioxide nanomesh is woven from titanium dioxide nanowires; the titanium dioxide nanowires include anatase-type titanium dioxide nanowires and rutile-type titanium dioxide nanowires. The mixed crystal-type titanium dioxide phase improves a catalytic activity of the composite for electrocatalysis; meanwhile, the titanium dioxide nanowires are further loaded with graphitic carbon particles to improve an overall conductivity of the composite for electrocatalysis. Therefore, the composite for electrocatalysis has a high electron mobility to achieve an improved electrocatalytic activity, which can be applied to the degradation of organic pollutants by electrocatalysis.
