Wood-derived catalyst boosts green chemical production and hydrogen energy

A study demonstrates how a renewable material as simple as wood can help transform biomass into valuable chemicals while simultaneously producing clean hydrogen fuel, offering a promising pathway toward sustainable chemical manufacturing.

Researchers have developed a novel electrocatalyst made from carbonized wood decorated with iron-doped cobalt phosphide nanostructures. This material enables the efficient conversion of 2,5-furanedimethanol, a stable biomass-derived compound, into 2,5-furandicarboxylic acid, a key building block for biodegradable plastics. At the same time, the system generates hydrogen gas, a clean energy carrier.

“By using natural wood as a structural platform, we were able to significantly enhance both catalytic activity and stability,” said one of the study’s authors. “This work shows that renewable materials can play an important role in next-generation energy and chemical technologies.”

2,5-furandicarboxylic acid, often abbreviated as FDCA, is considered one of the most important bio-based platform chemicals. It can replace petroleum-derived components in plastics such as polyethylene terephthalate, helping reduce reliance on fossil resources. However, producing FDCA efficiently and sustainably has remained a challenge, especially when using stable precursors like 2,5-furanedimethanol.

To address this, the research team designed a bifunctional catalyst that can drive both oxidation and hydrogen evolution reactions within a single system. The catalyst uses carbonized wood as a three-dimensional scaffold. Its natural porous structure provides abundant channels for mass transport and exposes a large number of active sites.

According to the study, the catalyst achieved a current density of 100 milliamps per square centimeter at relatively low voltage while delivering a high FDCA yield of about 90 percent. It also maintained stable performance for more than 100 hours under strongly alkaline conditions.

Importantly, the system avoids a common limitation seen in conventional catalysts. In many cases, organic molecules interfere with hydrogen production at the cathode. In contrast, the wood-based catalyst maintained strong hydrogen evolution performance even in the presence of the biomass substrate.

This resulted in a hydrogen production rate more than three times higher than that of traditional noble metal systems such as platinum and iridium oxide. The process also achieved near 100 percent Faradaic efficiency, indicating that almost all electrical energy was effectively converted into chemical products.

The key to this performance lies in both material design and atomic-level engineering. The researchers showed through theoretical calculations and experiments that introducing iron into cobalt phosphide improves the adsorption and reaction pathways involved in the oxidation process. Meanwhile, the hierarchical structure of the wood-derived carbon enhances electron transport and accessibility of catalytic sites.

Beyond performance, the approach offers practical advantages. Natural wood is abundant, low-cost, and environmentally friendly. Using it as a catalyst support reduces reliance on expensive synthetic materials and simplifies fabrication.

The study highlights a broader concept of integrating biomass conversion with energy production. Instead of treating chemical manufacturing and hydrogen generation as separate processes, the system couples them into a single, more efficient pathway.

“This integrated strategy could help lower energy consumption while producing both high-value chemicals and clean fuel,” the authors noted.

The findings open new opportunities for designing sustainable electrocatalytic systems based on renewable resources, with potential applications in green chemistry, energy storage, and carbon-neutral technologies.
