Bioenergy possesses the potential to alleviate our energy demands while maintaining renewability and carbon neutrality. The utilization of abundant biomass sources for bioenergy production presents a significant challenge. When considering chemical processes for conversion, the development of effective catalysts becomes imperative as they play a pivotal role in biomass-to-bioenergy/biofuel conversion. In such scenarios, heterogeneous nanoporous materials emerge as crucial components for facilitating catalytic conversion. This perspective provides a comprehensive summary of biomass, including its classification, valorization processes and applications along with recent advancements in various catalytic systems utilized for transforming biomass and its intermediates into renewable energy products. We delved into the diverse classes of heterogeneous catalysts, including metal-based, metal oxide-based, silica based, hybrid catalysts, and organic polymers, highlighting their unique structural and compositional features that influence catalytic activity and selectivity. Furthermore, we discussed the importance of pore structure, surface area, and active site accessibility in enhancing catalytic performance. By examining the advantages and limitations of different catalysts, we provide insights into the rational design and optimization of porous heterogeneous catalysts for efficient and sustainable bioenergy conversion. This perspective serves as a valuable resource for researchers and engineers in the field of renewable energy, seeking to develop innovative catalyst materials for biomass valorization.

“…The grass is harvested post-frost and milled, then it is processed to yield fermentable sugars by chemical and biological catalysis (Scheme 1), which involves pretreating, and hydrolyzing with cellulases and associated enzymes. The most common pretreatment consists of reacting the biomass with heated dilute sulfuric acid, which directly hydrolyzes xylan and activates the cellulose for enzymatic cleavage, as recently reviewed [1]. Dilute sulfuric acid pretreatment offers low costs and versatility with a wide range of severities for the highly efficient pretreatment of a variety of biomass types [2].…”

Amino acids have relevance in biorefining as fermentation nutrients but also as valued coproducts obtainable from plant biomass. Soy flour was studied as a representative low-cost protein source requiring hydrolysis to free primary amino acids for utilization. Within the context of biorefining, process schemes, reactant concentrations, times, and temperatures were varied to explore the efficiency of dilute sulfuric acid hydrolysis of soy flour to release amino acids. Two process strategies were optimized. Either soy flour was co-processed with switchgrass biomass using a dilute-acid pretreatment, or it was hydrolyzed alone with dilute acid. Significant improvement to hydrolysate fermentability was accomplished by adding 2.5–10 g/L soy flour to switchgrass pretreatment with dilute sulfuric acid (0.936% v/v) for 15 min at 160 °C. This practice optimized accumulation of neutral sugars and resulted in a 25% reduction in furfural while boosting xylose 7% and up to doubling primary amino nitrogen (PAN), as compared to no soy flour addition to switchgrass pretreatment. When soy flour was hydrolyzed alone, PAN titers were optimized to 1588 mg N/L (9.9 g amino acids/L) and yield to 0.0529 g PAN/g flour (61% of theoretical) using a 10% (v/v) (1.8 M) sulfuric acid hydrolysis 30 min at 160 °C.
