Abstract Algae, which contains most of the marine biogenic sulfur (S), is the main producer of dimethylsulfide (DMS). The oxidation products of DMS (methanesulfonic acid (MSA) and non-sea salt sulfates (nss-SO42-)) are important contributors to acid rain acidity (~ 40%) and have great influence on global climate change and acid rain formation. The biogenic S of red algae mainly exists in carrageenan molecules, the polysaccharide extract of red algae. In this work, the carrageenan biogenic S was fixed into biochar aerogel (SCA) synchronically by pyrolysis with the assistance of the unique hydrogel property of carrageenan. During this process, 89% of C and 96% of marine biogenic S are preserved in SCA, efficiently preventing the loss of C and S element. More importantly, the thiophene S structure in SCA framework derived from the marine biogenic S could endow the carbon aerogel superior electrocatalysis activity by regulating the charge density of adjacent C atoms. For instance, thiophene S structure can promote the cleavage and protonation of N2 molecules and efficiently lower the energy barrier of the promote the protonation of N2, thus greatly enhance the activity of electrocatalytic NRR. This study provided a promising avenue for the synchronization fixation of marine biogenic S and C to reduce the the formation of acid rain and carbon dioxide emissions. It also developed a green and sustainable way to synthesize high-performance biochar materials for advanced energy conversion.

Mechanisms for catalytic SO2 transformation to H2SO4 over clay dusts have been unraveled at a molecular level. All O atoms in ozone (especially molecular oxygen) are effective oxidants due to remarkable promotion of a vicinal Al3+ site.
