[PMID: 36627240 DOI: 10.1002/anie.202218115] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/04/2023] [Accepted: 01/10/2023] [Indexed: 01/12/2023]
Abstract
It is highly desired to achieve controllable product selectivity in CO2 hydrogenation. Herein, we report light-induced switching of reaction pathways of CO2 hydrogenation towards CH3 OH production over actomically dispersed Co decorated Pt@UiO-66-NH2 . CO, being the main product in the reverse water gas shift (RWGS) pathway under thermocatalysis condition, is switched to CH3 OH via the formate pathway with the assistance of light irradiation. Impressively, the space-time yield of CH3 OH in photo-assisted thermocatalysis (1916.3 μmol gcat -1 h-1 ) is about 7.8 times higher than that without light at 240 °C and 1.5 MPa. Mechanism investigation indicates that upon light irradiation, excited UiO-66-NH2 can transfer electrons to Pt nanoparticles and Co sites, which can efficiently catalyze the critical elementary steps (i.e., CO2 -to-*HCOO conversion), thus suppressing the RWGS pathway to achieve a high CH3 OH selectivity.

Abstract
Herein, we report the synthesis of photoactive polymeric organo-sulfur (POS) materials. These polymers absorb light in the ultraviolet/visible and near-infrared region of the solar spectrum, and upon irradiation, they reduce water to hydrogen (H2 ). The decoration of POS materials with nitrile (-CN) groups is found to be the critical factor for enhanced interactions with the co-catalyst, Ni2 P, leading to greater H2 evolution rates compared to the nitrile-free POS material.

Abstract
Photosensitization associated with electron/energy transfer represents the central science of natural photosynthesis. Herein, we proposed a protocol to dramatically improve the sensitizing ability of metal-organic frameworks (MOFs) by switching their excited state distribution from 3 MLCT (metal-to-ligand charge transfer) to 3 IL (intraligand). The hierarchical organization of 3 IL MOFs and Co/Cu catalysts facilitates electron transfer for efficient photocatalytic H2 evolution with a yield of 26 844.6 μmol g-1 and CO2 photoreduction with a record HCOOH yield of 4807.6 μmol g-1 among all the MOF photocatalysts. Systematic investigations demonstrate that strong visible-light-absorption, long-lived excited state and ingenious multi-component synergy in the 3 IL MOFs can facilitate both interface and intra-framework electron transfer to boost photocatalysis. This work opens up an avenue to boost solar-energy conversion by engineering sensitizing centers at a molecular level.

Abstract
CO 2 hydrogenation to methanol has attracted great interest while suffering from low conversion and high energy input. Herein, tiny Pd 3 Cu nanoparticles are confined into a metal-organic framework (MOF), UiO-66, to afford Pd 3 Cu@UiO-66 for CO 2 hydrogenation. Remarkably, it achieves a methanol production rate of 340 µmol g -1 h -1 at 200 °C and 1.25 MPa under light irradiation, far surpassing that in the dark. The photo-generated electron transfer from the MOF to antibonding orbitals of CO 2 * promotes CO 2 activation and HCOO* formation. In addition, the Pd 3 Cu microenvironment plays a critical role in CO 2 hydrogenation. In contrast to the MOF-supported Pd 3 Cu (Pd 3 Cu/UiO-66), the Pd 3 Cu@UiO-66 exhibits a much higher methanol production rate due to the close proximity between CO 2 and H 2 activation sites, which greatly facilitates their interaction and conversion. This work provides a new avenue to the integration of solar and thermal energy for efficient CO 2 hydrogenation under moderate conditions.

Abstract
The exploitation of highly efficient carbon dioxide reduction (CO2 RR) electrocatalyst for methane (CH4 ) electrosynthesis has attracted great attention for the intermittent renewable electricity storage but remains challenging. Here, N-heterocyclic carbene (NHC)-ligated copper single atom site (Cu SAS) embedded in metal-organic framework is reported (2Bn-Cu@UiO-67), which can achieve an outstanding Faradaic efficiency (FE) of 81 % for the CO2 reduction to CH4 at -1.5 V vs. RHE with a current density of 420 mA cm-2 . The CH4 FE of our catalyst remains above 70 % within a wide potential range and achieves an unprecedented turnover frequency (TOF) of 16.3 s-1 . The σ donation of NHC enriches the surface electron density of Cu SAS and promotes the preferential adsorption of CHO* intermediates. The porosity of the catalyst facilitates the diffusion of CO2 to 2Bn-Cu, significantly increasing the availability of each catalytic center.
