Multi-heteroatom-doped porous carbon electrodes from 3D printing and conformal carbonization of ionic liquids for electrocatalytic CO₂ conversion into syngas.

ABSTRACT: 3D printing as an advanced manufacturing technique provides an alternative cost-effective option for design and preparation of porous catalytic electrodes. Herein, carbonaceous catalytic electrodes with ternary dopants of boron (B), phosphorous (P), and nitrogen (N) (termed BPN-3Dp-CCEs) were successfully engineered via combination of the 3D printing technique and the following conformal carbonization of ionic liquid. The as-made electrodes were in turn applied to electrify CO₂ into syngas in a controllable composition of a H₂:CO molar ratio of 0.32-3.46. Notably, the BPN-3Dp-CCEs have tailored 3D macroscopic shapes of self-supporting skeletons, and due to ternary doping, demonstrated promoted catalytic activity in the electrocatalytic CO₂ conversion into s
