Abstract：

Desulfurization　sorbent　with　a　high　active　component　utilization　is　of　importance　for　the　removal　of　H2S　from　coal　gas　at　high　temperatures.　Thus,　the　hypothesis　for　producing　ZnxCo3-xO4/carbon　nanofiber　sorbents　via　the　combinations　of　electrospinning,　in　situ　hydrothermal　growth,　and　carbonization　technique　has　been　rationally　constructed　in　this　study.　ZnxCo3-xO4　nanoparticles　derived　from　metal-organic　frameworks　are　uniformly　loaded　on　the　electrospun　carbon　nanofibers　(CNFs)　with　high　dispersion.　ZnxCo3-xO4/CNFs　sorbents　possess　the　highest　breakthrough　sulfur　adsorption　capacity　(12.4　g　S/100　g　sorbent)　and　an　excellent　utilization　rate　of　the　active　component　(83.2%).　The　excellent　performance　of　ZnxCo3-xO4/CNFs　can　be　attributed　to　the　synergetic　effect　of　the　hierarchical　structure　and　widely　distributed　ZnxCo3-xO4　on　the　CNFs　supporter.　The　decomposition　of　Zn/Co-ZIFs　not　only　generates　the　nucleus　of　oxides　but　also　realizes　their　physical　isolation　through　the　formation　of　carbon　grids　on　the　surface　of　CNFs,　avoiding　the　aggregation　of　oxides.　Furthermore,　ZnxCo3-xO4/CNFs　sorbents　show　an　overwhelming　superiority　over　the　ZnO/CNFs　sorbent,　which　is　attributed　to　the　introduction　of　Co　and　then　the　promotion　of　the　stability　of　Zn　at　high　temperatures.　The　presence　of　Co　also　accelerates　the　adsorption　of　H2S　on　the　active　site　of　the　oxide　surface.　The　presented　method　is　beneficial　for　promoting　desulfurization　performances　and　producing　sorbents　with　high　utilization　of　active　components.　©　2022　American　Chemical　Society.
