Metal–air batteries, such as zinc–air, are known for their high specific capacity and environmental friendliness. Operational longevity energy efficiency, however, remain constrained by sluggish reaction kinetics, elevated overpotential, interfacial instability during charge–discharge cycles. While noble metal catalysts have historically addressed these gaps, strategic resource allocation now prioritizes abundant, commercially reachable, cost‐effective alternatives. Biomass, a sustainable resource, is crucial in the development of metal‐free heteroatom‐doped biomass carbon nanostructured electrocatalysts porous air electrodes with excellent performance batteries. These novel materials emerge critical enablers, leveraging inherent heteroatom density, tunable pore architectures, potential transition doping codoping to optimize bifunctional activity.

This study investigates a continuous deoxygenation of bio-oil vapor in catalytic fixed-bed reactor coupled to drop tube (DTR) for biomass pyrolysis. Beech wood pyrolysis was initially examined without catalysts at various temperatures (500–600 °C). The products were characterised using GC-MS, Karl Fischer titration, GC-FID/TCD, and thermogravimetric analysis. highest yield (58.8 wt.%) achieved 500 °C with mL/min N2 flow rate. Subsequently, ex situ performed an HZSM-5 catalyst DTR outlet, operating 425 °C, 450 °C. exhibited declining efficiency over time, which evidenced by decreasing conversion rates chemical families. Principal component analysis employed interpret the complex dataset, facilitating visualisation relationships between experimental conditions product compositions. highlights challenges operation as durations limited 120 min due clogging issues. research contributes understanding deoxygenation, providing insights into configuration, process parameters, performance crucial developing efficient sustainable biofuel production processes.
