Amidst the rapid expansion of the global economy, the demand for energy has escalated. The depletion of traditional energy sources coupled with environmental pollution concerns has catalyzed a shift towards the development and utilization of clean, renewable energy. Biogas, as a renewable energy source, provides diverse applications and holds the potential to alleviate energy shortages. Recently, biogas dry reforming technology has garnered substantial attention as a significant pathway for renewable energy utilization, particularly in the development and optimization of catalysts. Contemporary research predominantly focuses on enhancing the activity and stability of catalysts, with particular emphasis on their resistance to coking and sintering. This review delineates the classification of biogas dry reforming catalysts, their catalytic activity, and issues related to carbon deposition, contrasting biogas dry reforming with traditional dry reforming in catalyst design. It synthesizes numerous studies from recent years aimed at mitigating carbon deposition during the biogas dry reforming process and boosting catalytic activity via active components, carriers, and promoters in both precious and non-precious metal catalysts. Furthermore, it discusses the current challenges of biogas dry reforming technology and outlines prospective future development trends. This discussion provides an in-depth understanding of biogas dry reforming technology and catalyst design, offering insights and recommendations for future research and industrial applications.

In the vast landscape of materials science, bismuth emerges as a compelling element with unique properties and diverse applications.

This work demonstrates enhanced photothermal catalytic performance for dry reforming of methane through a strategic Pr/Ni loading sequence on CeO ₂ , achieving 80.1% CH ₄ and 83.1% CO ₂ conversions with an ideal H ₂ /CO ratio of 1.0.

The substantial presence of nitrogen oxides (NO and NO2) in outdoor environments detrimentally impacts natural ecosystems and exerts significant influence on urban climates. Conventional NOx treatment methods frequently suffer from challenges such as harsh reaction conditions and high energy consumption. Consequently, the development of advanced photocatalytic systems to efficiently degrade NOx while minimizing the formation of toxic byproducts represents a critical challenge in environmental catalysis. In this study, a novel ternary composite material (5% Mo-CN/InP-NBOC) was constructed via hydrothermal synthesis and surface modification strategies, achieving 42% NO oxidation efficiency under visible light irradiation with a mere 0.9% NO2 generation rate. This performance demonstrates efficient photocatalytic NO oxidation while effectively suppressing NO2 production. Systematic characterization techniques, including XRD, TEM, and XPS, confirmed the successful integration of InP quantum dots (5–10 nm) and amorphous Mo-CN onto NBOC nanosheets, forming an intimate heterojunction structure. PL and ESR analyses revealed that Mo-CN enhances charge carrier separation and governs the NO oxidation process through the activation of dual free radical pathways (•O2⁻ and •OH). This work establishes a "quantum dot-primary catalyst-cocatalyst" ternary collaborative design paradigm, providing experimental evidence and theoretical models to address the challenges of synergistic optimization among activity, selectivity, and stability in photocatalytic NOx treatment.
