Developing efficient metal‐free catalysts for lignin valorization is essential but challenging. In this study, a cost‐effective strategy is employed to synthesize a P, N co‐doped carbon catalyst through hydrothermal and carbonization processes. This catalyst effectively cleaved α‐O‐4, β‐O‐4, and 4‐O‐5 lignin linkages, as demonstrated with model compounds. Various catalysts were prepared at different carbonization temperatures and thoroughly characterized using techniques such as XRD, RAMAN, FTIR, XPS, NH3‐TPD, and HRTEM. Attributed to higher acidity, the P5NC‐500 catalyst exhibited the best catalytic activity, employing H2O2 as the oxidant in water. Additionally, this metal‐free technique efficiently converted simulated lignin bio‐oil, containing all three linkages, into valuable monomers. Density Functional Theory calculations provided insight into the reaction mechanism, suggesting substrate and oxidant activation by P‐O‐H sites in the P5NC‐500, and by N‐C‐O‐H in the CN catalyst. Moreover, the catalyst's recyclability and water utilization enhance its environmental compatibility, offering a highly sustainable approach to lignin valorization with potential applications in various industries.

In this study chitin derived from shrimp shells was used in the design of heterogeneous Pd‐based catalysts for Heck and Suzuki‐Miyaura cross‐coupling reactions. The synthesis of Pd nanoparticles supported on N‐doped carbons was performed through different approaches, including a sustainable mechanochemical approach, by using a twin‐screw extruder. All catalytic systems were characterized by a multitechnique approach and the effect of nanoparticles size, N‐doping on the support, and their synergistic interactions were elucidated. Specifically, Kelvin Probe Atomic Force Microscopy provided valuable insights on charge transfer and metal‐support interactions. The catalytic behaviour of the samples was investigated in cross‐coupling reactions under batch conditions and under semi‐continuous flow solvent‐free conditions, respectively obtaining a quantitative yield and a noteworthy productivity of 8.7 mol/(gPdh).

Multifunctional catalysts have received considerable attention in the cascade reactions of biomass processing. A cascade (or tandem) reaction is realized when multiple reaction steps that require different catalysts are performed in a one-step process. These reactions require bi- or multifunctional catalysts or catalyst mixtures to serve successfully at each reaction step. In this review article, we discuss the major factors of the catalyst design influencing the structure–property relationships, which could differ depending on the catalyst type. The major factors include the amounts and strengths of acidic and basic sites, interactions between those and metal sites, synergetic effects, nanoparticle sizes and morphology, nanostructures, porosity, etc. The catalysts described in this review are based on zeolites, mesoporous solids, MOFs, and enzymes. The importance of continuous cascade processes is also examined.
