“…Moreover, the AC‐B supported Pt catalyst produced 1.7 % FMA whereas with the AC‐S support, no FMA was produced. The formation of this relatively large condensation product was noticed to be favored by large pores by Jaatinen et al . The 3Pt/AC‐B catalyst had more mesopores than the 3Pt/AC‐S catalyst (Table ), which could explain the formation of FMA; however, no similar behavior was observed with Ru or Ni.…”

Bio‐based chemicals can be produced from furfural through hydrotreatment. In this study, 2‐methylfuran (MF), a potential biofuel component, was produced with Pt, Ru, and Ni catalysts supported on wood‐based activated carbons. The catalytic hydrotreatment experiments were conducted in a batch reactor at 210–240 °C with 2‐propanol as solvent and 40 bar H2 pressure. Two types of activated carbon supports were prepared by carbonization and activation of lignocellulosic biomass (forest‐residue‐based birch and spruce from Finland). Both types of activated carbons were suitable as catalyst supports, giving up to 100 % furfural conversions. The most important factors affecting the MF yield were the metal dispersion and particle size as well as reaction temperature. The highest observed MF yields were achieved with the noble metal catalysts with the highest dispersions at 240 °C after 120 min reaction time: 3 wt % Pt on spruce (MF yield of 50 %) and 3 wt % Ru on birch (MF yield of 49 %). Nickel catalysts were less active most likely owing to lower dispersions and incomplete metal reduction. Interesting results were obtained also with varying the metal loadings: the lower Pt loading (1.5 wt %) achieved almost the same MF yield as the 3 wt % catalysts, which can enable the production of MF with high yields and reduced catalyst costs. Based on this study, biomass‐based renewable activated carbons can be used as catalyst supports in furfural hydrotreatment with high conversions.

“…In our previous study, monometallic Ni catalysts are less active than noble metals, leading to the maximum MF yield of less than 40% [49]. However, the addition of Cu is known to significantly increase the catalytic activity of Ni [11,43]. Gong et al [31] have reported the beneficial combination of CuOx and Cu species on AC for MF production.…”

“…Prior to metal addition, the activated support materials were further washed with HNO3 and H2SO4 to modify their surface properties. The combination of Cu and Ni was selected as these metals were found to be beneficial for the hydrotreatment of furfural to produce MF [11,12,43].…”

“…Compared with single metal catalysts, bimetallic catalysts have unique synergistic effect, which may improve the activity and stability of catalysts. [84,86,88,90,[93][94][95]99,[101][102][103][104] The main synergistic effect of bimetallic catalysts is to enable the generation of new reaction sites [77][78][79]83,85,[96][97][98]105] and promote charge transfer. [87,91,96,97,106] The active sites can be geometrically and electronically modified by the above effects, and ultimately regulate their catalytic properties.…”

The transformation of renewable platform molecules to produce value‐added fuels and fine‐chemicals is a promising strategy to sustainably meet future demands. Owing to their finely modified electronic and geometric properties, carbon‐based nanocatalysts have shown great capability to regulate their catalytic activity and stability. Their well‐defined and uniform structures also provide both the opportunity to explore intrinsic reaction mechanisms and the site‐requirement for valorization of renewable platform molecules to advanced fuels and chemicals. This Review highlights the progress achieved in carbon‐based nanocatalysts, mainly by using effective regulation approaches such as heteroatom anchoring, bimetallic synergistic effects, and carbon encapsulation to enhance catalyst performance and stability, and their applications in renewable platform molecule transformations. The foundation for understanding the structure‐performance relationship of carbon‐based catalysts has been established by investigating the effect of these regulation methods on catalyst performance. Finally, the opportunities, challenges and potential applications of carbon‐based nanocatalysts are discussed.
