Abstract: This work summarizes the disciplinary connotation of ecological aesthetics, discusses the social and philosophical background of the origination of ecological aesthetics, and applies ecological aesthetics to the research on the production processes of catalytic materials. It is found that compared with conventional chemical processes, catalytic materials synthesized using green chemical processes that conform to ecological aesthetics have advantages in raw material cost, energy consumption, environmental protection, operational complexity, and product performance. Based on this, it is proposed that, as green chemical processes develop to a certain extent, they will unify anthropocentrism and ecocentrism, and meet both human needs and ecological protection requirements. The mentioned green chemical processes adopt biomass lotus leaf stems as a carbon source to produce non-noble metal bimetallic carbide (C 19 Cr 7 Mo 24 )-based catalysts for oxygen reduction reaction (ORR). Its initial half-wave potential (E 1/2 ) for catalyzing ORR in an alkaline medium is 0.903 V, the E 1/2 retention rate after 50,000 cycles is 98.9%, and its peak power density in H 2 /O 2 fuel cell reaches 1.47 W cm −2 , making it one of the most active non-noble metal catalysts for ORR reported so far; its stability is unparalleled.
