Van der Waals (VDW) heterojunctions in a 2D/2D contact provide the highest area for separation and transfer of charge carriers. In this work, top‐down strategy with gas erosion process was employed to fabricate carbon nitride VDW heterojunction (g‐C 3 N 4 ) carbon‐rich nitride. The created 2D semiconducting channel structure exhibits enhanced electric field exposure radiation absorption, which facilitates carriers their mobility. Consequently, compared bulk g‐C its nanosheets, photocatalytic...

Oxidative dehydrogenation of ethane with CO2 (ODEC) is an attractive reaction for reduction carbon footprints and ethene production. In this work, we present photothermal catalysis on confined bimetal catalysts ODEC. Carbon nanotubes non-noble alloy (i.e., CoNi@CNTs FeNi@CNTs) were prepared FeNi@CNTs showed effective performance in catalytic ODEC to ethene. Experiments simulations reveal that UV visible lights (420 – 490 nm) are responsible non-oxidative ethane, respectively, Additionally,...

Blended amines synthesize the absorption characteristics of different amine solvents and show a great potential in carbon capture. However, comprehensive techno-economic analysis (TEA) CO2 process using blended is still lacking. In this study, we investigated three solvents: MEA/MDEA, PZ/MEA, PZ/MDEA, with commercially available MEA used as benchmark. Rigorous simulation were applied to evaluate performance capture steel plant. molar loading lean solvent (αlean) stripper pressure (P)...

Integrating carbon nitride with graphene into a lateral heterojunction would avoid energy loss within the interlaminar space region on conventional composites. To date, its synthesis process is limited to bottom-up method which lacks targeting and homogeneity. Herein, we proposed hydrogen-initiated chemical epitaxial growth strategy at relatively low temperature for fabrication of graphene/carbon in-plane heterostructure. Theoretical experimental analysis proved that methane via in situ...
