Rejoint of Carbon Nitride Fragments into Multi-Interfacial Order-Disorder Homojunction for Robust Photo-Driven Generation of H O.

Photocatalytic technology based on carbon nitride (C N ) offers a sustainable and clean approach for hydrogen peroxide (H O ) production, but the yield is severely limited by the sluggish hot carriers due to the weak internal electric field. In this study, a novel approach is devised by fragmenting bulk C N  into smaller pieces (CN-NH ) and then subjecting it to a directed healing process to create multiple order-disorder interfaces (CN-NH -NaK). The resulting junctions in CN-NH -NaK significantly boost charge dynamics and facilitate more spatially and orderly separated redox centers.

Enhancing photocatalytic hydrogen production of carbon nitride: Dominant advantage of crystallinity over mass transfer.

Mass transfer enhancement and crystallinity engineering are two prevailing technologies for photocatalyst modification. However, their relative effectiveness in enhancing photocatalytic activity remains unclear due to the lack of rational probing catalysts. In this study, we synthesized two distinct carbon nitride (CN) catalysts: one with a high specific surface area (CN-HA) and the other with improved crystallinity (CN-HC).

China's Carbon Emissions and Trading Pilot, Political Connection, and Innovation Input of Publicly Listed Private Firms.

Taking China's carbon emissions and trading pilot (CCETP) as a quasi-natural experiment, this paper examines the impact of CCETP on publicly listed private firms' innovation input and the moderating effect of the firms' political connection based on the difference-in-differences model. The results show that CCETP has a significantly positive effect on the innovation input of Chinese publicly listed private firms. Moreover, the political connection of executives exhibits a positive moderating effect on CCETP's impact on innovation input.
