“…Amongst them, nickel based catalysts are the most used ones in both research and industrial processes. In fact, there are a lot of commercially available Ni catalysts and they are supported on a wide variety of materials, such as Al 2 O 3 , ZrO 2 , TiO 2 , CeO 2 , MgO and even olivine and dolomite natural ores [276][277][278][279][280][281][282]. Those catalysts have a high catalytic activity for tar removal.…”

“…Therefore, the tar reforming activity of the Ni x /N y HC-SF z composites at a mild temperature of 600 °C is compared favorably with that of previously reported biochar-supported catalysts at a higher temperature of 800 °C. Moreover, the light PAH reforming ability of the Ni x /N y HC-SF z composites is even higher or approaches that of the reforming of compounds such as benzene (54.4% at 700 °C) and toluene (92.3% at 700 °C, 94.8% at 500 °C, 100% at 600 °C), which are easier to be thermally reformed under mild temperatures by other biochar-supported catalysts. Consequently, taking into account the variation in biochar composition and tar properties, the synthesized Ni x /N y HC-SF z composites in this work are expected to decrease the energy consumption for the tar reforming process without compromising on reforming activity.…”

“…Recently, several Ni-based catalysts supported on different materials ( e.g. , biochar, , ceramic foam, graphitic carbon) have been successfully developed for the efficient steam reforming of biomass tar under mild temperatures (450–600 °C). Nonetheless, it is known that the composition of biomass tar is extremely complex, such as phenolic hydrocarbons, nonsubstituted aromatic hydrocarbons, alkylated aromatic hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). , Compared to nonsubstituted aromatic ( e.g.…”

A series of hydrothermal carbon-supported nickel catalysts with an Ageratum conyzoides L.-like superstructure derived from green and sustainable cellulose (Ni x /N y HC-SF z ) were fabricated by a facile soft template/nitrogen co-directed hydrothermal assembly strategy. The soft template and nitrogen doping into the hydrothermal carbon framework not only dictated specific morphological evolution for creating the architecture with a mesoporous texture but also significantly tuned the electronic properties of the composites with strong metal−support interactions. Benefiting from these unique characteristics as well as systematic control of the experimental conditions, the hierarchical structured Ni x /N y HC-SF z composites served as promising catalysts with desirable low-temperature tar reforming activity and long-term durability. In particular, the N 0.2 /N 2 HC-SF 3 composite exhibited a maximum naphthalene conversion of 87.6%, while the N 0.2 / N 4 HC-SF 3 composite demonstrated an optimum H 2 selectivity of 81.2% at a mild temperature of 600 °C. For the Ni 0.2 /N 2 HC-SF 3 composite, more than 92.8% of the initial naphthalene conversion and 86.5% of initial H 2 selectivity were still retained after 10 consecutive cycles. Given the chemical tunability of both active metal species and precursory carbon sources in this fabrication system, we envisioned that the general design principle of low-cost yet high-performance nonprecious nickel catalysts in this work could be extended to the construction of other biochar-based nanomaterials for specific catalytic applications.

We conceptualize bioresource upgrade for sustainable energy, environment, and biomedicine with a focus on circular economy, sustainability, and carbon neutrality using high availability and low utilization biomass (HALUB). We acme energy-efficient technologies for sustainable energy and material recovery and applications. The technologies of thermochemical conversion (TC), biochemical conversion (BC), electrochemical conversion (EC), and photochemical conversion (PTC) are summarized for HALUB. Microalgal biomass could contribute to a biofuel HHV of 35.72 MJ Kg−1 and total benefit of 749 $/ton biomass via TC. Specific surface area of biochar reached 3000 m2 g−1 via pyrolytic carbonization of waste bean dregs. Lignocellulosic biomass can be effectively converted into bio-stimulants and biofertilizers via BC with a high conversion efficiency of more than 90%. Besides, lignocellulosic biomass can contribute to a current density of 672 mA m−2 via EC. Bioresource can be 100% selectively synthesized via electrocatalysis through EC and PTC. Machine learning, techno-economic analysis, and life cycle analysis are essential to various upgrading approaches of HALUB. Sustainable biomaterials, sustainable living materials and technologies for biomedical and multifunctional applications like nano-catalysis, microfluidic and micro/nanomotors beyond are also highlighted. New techniques and systems for the complete conversion and utilization of HALUB for new energy and materials are further discussed.
