Tuning B–N pairs in porous carbon nanorods for electrochemical conversion of CO₂ to syngas with controllable CO/H₂ ratios

Abstract

The direct electroreduction of CO2 into syngas with controllable CO/H2 ratios is a promising approach to rebalance the CO2 cycle and storage intermittent renewable energy. However, it is still challenging...

C60 and Derivatives Boost Electrocatalysis and Photocatalysis: Electron Buffers to Heterojunctions

“…Carbon-based, metalfree catalysts are however potential practical substitutes for noble metal-based catalysts because of good catalytic activity, selectivity and stability. [225][226][227][228][229][230] It is concluded that C 60 and derivatives are significant to development of increasingly efficient and advanced electrocatalysts and photocatalysts. This is because of electron acceptor properties, distinctive heterostructure(s) and physicochemical characteristics and electron buffers, together with high structural integrity.…”

Ligand-engineering Cu-based catalysts to accelerate the electrochemical reduction of CO2

“…[1][2][3][4] Nevertheless, the inherent complexity of the eCO 2 RR process presents significant challenges in controlling its activity and specific product selectivity. 5,6 Although various catalysts have been designed to upgrade the performance of the eCO 2 RR over the past few years, [7][8][9][10][11][12] several obstacles still need to be overcome regarding their selectivity, activity, and durability. Therefore, designing efficient eCO 2 RR catalysts for effective CO 2 conversion is one of the most urgent tasks.…”

Electroreduction of CO2 to syngas with controllable H2/CO ratios in a wide potential range over Ni–N co-doped ultrathin carbon nanosheets

“…Fig.5Recently reported H 2 /CO ratios of various catalysts used for syngas production at different applied potentials. (a) Heteroatom-doped carbon catalysts (N-CNTs,42 BPNC,14 NCSP-70,51 UNCNs-900,52 NCN-6,53 and NBC54 ), (b) metal catalysts (OD-Cu NA,55 ZnOCNT,56 I-Ag,57 AuCu 2 /CNT,58 Au Θ Cu ∼ 3/3,59 and Co rate-aligened60 ), (c) M-N-C single-atom catalysts (Ni-hG,23 CoNi-NC,24 Co-N-C-Ph,61 Fe-N-C,33 P/Ni-4@Ni-NC,62 and Co@CoNC-90063 ) and (d) Ni-N co-doped ultrathin carbon nanosheet electrodes. The shaded regions are the areas with the optimal syngas ratios.…”
