Direct Laser Writing-Assisted Method for Template-Free Fabrication of Biomass-Based Porous Carbon Platelets with Uniform Size and Arbitrarily Designed Shapes.

ABSTRACT: Because of a wide range of applications of porous carbon platelets (PCPs), a robust method for their facile synthesis/fabrication with controlled porous structure, size, and shape is constantly needed. Herein, we report a simple and scalable method for producing PCPs with uniform size and arbitrarily designed shapes. This approach relies on CO₂ laser irradiation to induce carbonization of a biomass composite sheet formed by the infusion of sodium lignosulfonate into a cellulose paper to create porous carbon features with arbitrarily designed shapes. Upon subsequent water immersion treatment, the laser-written carbon features could spontaneously detach to form freestanding PCPs. The PCPs of different shapes were fabricated, characterized, and demonstrated for their potential appl
