Towards improving H2S catalytic oxidation on porous carbon materials at room temperature: A review of governing and influencing factors, recent advances, mechanisms and perspectives

Self-supporting nano-porous carbon nanosheet with organized sp2-C network for unprecedented catalytic performance in room-temperature H2S oxidization

“…The catalytic oxidation of H 2 S on carbon-based materials at room temperature is a complex process, recognized as a gasliquid-solid three-phase reaction. [55][56][57] H 2 S diffuses into the pore system and dissociates to HS − at the local environment formed by the water lm and alkaline site. The HS anions are oxidized by reactive oxygen to sulfur, and that sulfur is deposited in the pores of the materials.…”

Advances in Resources Recovery of H2S: A Review of Desulfurization Processes and Catalysts

“…Besides, only sulfur is recycled in the Claus process, while hydrogen is wasted and SO 2 is unavoidably emitted. Therefore, advanced desulfurization strategies have been developed to recover sulfur and hydrogen from H 2 S, including selective oxidation of H 2 S, − splitting of H 2 S, , and simultaneous conversion of CO 2 and H 2 S, , etc.…”

Tuning the metal valence state of Pd nanoparticles via codoping of B–N for chlorophenol hydrodechlorination

“…[25][26][27] Currently, a great number of synthesis methods are employed to synthesize HOPC, among which template methods are commonly used. [28][29][30] Compared with the hard template method, the soft template method is considered as a suitable and low-pollution method in which it removes the surfactant in the process of high-temperature carbonization and thus escapes from the time-consuming washing. Under the synergistic effect of hydrogen bond and hydrophobic interactions, the soft template assembles with the carbon precursors which can introduce some doped atoms.…”
