Hierarchical porous carbon catalyst derived from sodium lignosulfonate for efficient biodiesel production: high turnover frequency and economic viability.

Sodium lignosulfonate, a major byproduct of the sulfite pulping industry, can be converted into carbonaceous materials for catalyst preparation, enabling high‑value utilization of industrial waste. In this study, a hierarchical porous carbon support (HPC) was prepared from sodium lignosulfonate and sodium humate throug...
