Abstract

The invention discloses a BC / G / MPc ternary composite catalyst and an in-situ synthesis method thereof. The composite catalyst takes bacterial cellulose / graphene as a carrier, the metal phthalocyanineis tetrasulfonic metal phthalocyanine, and the central metal M of the metal phthalocyanine is one of manganese, iron, cobalt, nickel, copper or zinc ions; immobilization between the metal phthalocyanine and the bacterial cellulose / graphene is realized through pi-pi interaction between the graphene and metal phthalocyanine molecules; the synthesis method comprises the following steps: adding a graphene dispersion liquid subjected to ultrasonic treatment and a tetrasulfonic metal phthalocyanine solution into a bacterial cellulose basal culture medium, and statically culturing acetobacter xylinumat 30 DEG C; and cleaning the obtained product with a hydrochloric acid solution, a sodium hydroxide solution and ultrapure water to obtain the BC / G / MPc ternary composite catalyst. The bacterial BC / G / MPc ternary composite catalyst prepared by adopting the technical scheme has the advantages of simple equipment, simple and convenient process, easiness in post-treatment, easiness in operation and the like.

Description

technical field [0001] The invention relates to a method for in-situ biosynthesis of bacterial cellulose / graphene / metal phthalocyanine (BC / G / MPc) composite catalyst, belonging to the fields of materials, chemistry and chemical industry. Background technique [0002] Metal phthalocyanine is a 18π-electron conjugated macrocyclic compound composed of four symmetrical isoindole units connected by imine bridges. There is a hole in the ring that can accommodate most elements in the periodic table of elements. Meanwhile, the hydrogen atoms on the benzene ring of the metal phthalocyanine outer ring can be replaced by various substituents. By changing the types of central metal and outer ring substituents, metallophthalocyanine derivatives with different physical and chemical properties can be obtained. The special structure of metallophthalocyanine leads to the following characteristics: (1) π electrons are conjugated on the entire macrocycle, and the entire conjugated molecule pre...
