Incorporating environmentally benign flame retardants as dopants in the co-pyrolysis of biomass to carbon materials offers a novel pathway for fabricating hierarchical porous structures with tailored heteroatom functional groups. This study pioneers a sustainable strategy to convert bamboo waste into heteroatom-doped hierarchical porous carbon for supercapacitors via a two-stage pyrolysis, using eco-friendly nitrogen-phosphorus flame retardants as dual-functional dopants. By integrating guanidine phosphate into bamboo co-pyrolysis (300°C, GP/bamboo ratio 1:2) followed by KHCO<sub>3</sub> activation, the optimal GB12 achieves 387 F/g at 0.5 A/g and 300 F/g at 20 A/g with 77.52 % capacitance retention, outperforming conventional doping methods. Remarkably, low-dose GP doping enables synergistic pore engineering (specific surface area of 1545.8 m²/g) and heteroatom functionality (3.42 % N, 0.49 % P), yielding a symmetric supercapacitor with 8.82 Wh/kg energy density at 125 W/kg.

In catalysis, special attention is given to the development of single-atom and bimetallic catalysts, which offer improved control over CNT growth, greater efficiency, and enhanced sustainability due to their recyclability. Studies on catalyst preparation and activation mechanisms highlight how atomic dispersion and thermal stability significantly affect CNT morphology and yield.

Optimizing synthesis conditions, including temperature regulation, carrier gas selection, and reaction time, has further refined control over CNT growth kinetics and structural properties.
