Abstract

A high-sulfur petroleum coke-based sulfur self-doped mesoporous carbon-supported Fe-TM bimetallic alloy catalyst, and a preparation method and use thereof are provided. The catalyst is an Fe-TM solid-solution alloy material supported on sulfur self-doped mesoporous carbon, formed by calcination under an inert atmosphere and reduction calcination under a hydrogen atmosphere after activation of high-sulfur petroleum coke by potassium ferrate. The catalyst can significantly reduce the peak dehydrogenation temperature of magnesium-based materials by 80 to 110 K. The catalytic effect is comparable to that of catalysts prepared by conventional routes, but the catalyst exhibits remarkable cost-effectiveness and environmental advantages, demonstrating the significant industrialization potential of high-sulfur petroleum coke in the field of hydrogen storage.

Dependent claims

A high-sulfur petroleum coke-based sulfur self-doped mesoporous carbon-supported Fe-TM bimetallic solid-solution alloy catalyst, comprising:

(a) a sulfur self-doped mesoporous carbon support, wherein sulfur originates from high-sulfur petroleum coke and migrates during a reduction calcination process and is self-doped into a carbon framework structure of the sulfur self-doped mesoporous carbon support;
and
(b) an Fe-TM bimetallic solid-solution alloy supported on the sulfur self-doped mesoporous carbon support;
wherein the high-sulfur petroleum coke has a sulfur content of 3 to 10 wt %;
and
wherein TM is a transition metal selected from chromium, manganese, cobalt, nickel, niobium, or copper.
