“…Zhaoyin and co-workers reported that Pd nanoparticles (3.1 nm) supported on carbon achieved a GLCEA yield of 47% and that the catalyst was reused six times without significant loss of catalytic activity [190]. The GLCEA yield could be increased to 56–62% by changing the carbon support to multi-wall carbon nanotubes (MWCNTs) [191], sulfur-treated multi-wall carbon nanotubes (S-MWCNTs) [192], and gas-phase sulfonated mesoporous polydivinylbenzene (SPDVB) [193], while the catalytic activity or leaching of the Pt species out of the support could be decreased.…”

In recent decades, the substitution of non-renewable fossil resources by renewable biomass as a sustainable feedstock has been extensively investigated for the manufacture of high value-added products such as biofuels, commodity chemicals, and new bio-based materials such as bioplastics. Numerous solid catalyst systems for the effective conversion of biomass feedstocks into value-added chemicals and fuels have been developed. Solid catalysts are classified into four main groups with respect to their structures and substrate activation properties: (a) micro- and mesoporous materials, (b) metal oxides, (c) supported metal catalysts, and (d) sulfonated polymers. This review article focuses on the activation of substrates and/or reagents on the basis of groups (a)–(d), and the corresponding reaction mechanisms. In addition, recent progress in chemocatalytic processes for the production of five industrially important products (5-hydroxymethylfurfural, lactic acid, glyceraldehyde, 1,3-dihydroxyacetone, and furan-2,5-dicarboxylic acid) as bio-based plastic monomers and their intermediates is comprehensively summarized.

“…33,34 In this manner, sole surface adsorption of the acid groups can be suppressed, while covalent bonding becomes favoured. First attempts to implement sulfuric species within CTF materials were described by Bai et al 35 Utilizing thiourea and thiosemicarbazide during a polymerization step with cyanuric chloride resulted in sulfur containing CTF materials with high sorption capacities and selectivities for uranium(VI).…”

“…Generally, the sulfonation of materials can be carried out in the liquid or the gas phase with sulfuric acid or oleum as a sulfonation agent. [30][31][32][33][34] Prior studies could not conrm the sulfonation of CTF materials in the liquid phase.…”

Covalent triazine-based frameworks (CTFs) were synthesized in large scale from various monomers. The materials were post-synthetically modified with acid functionalities via gas-phase sulfonation. Acid capacities of up to 0.83 mmol g À1 at sulfonation degrees of up to 10.7 mol% were achieved. SulfonatedCTFs exhibit high specific surface area and porosity as well as excellent thermal stability under aerobic conditions (>300 C). Successful functionalization was verified investigating catalytic activity in the acidcatalyzed hydrolysis of cellobiose to glucose at 150 C in H 2 O. Catalytic activity is mostly affected by porosity, indicating that mesoporosity is beneficial for hydrolysis of cellobiose. Like other sulfonated materials, S-CTFs show low stability under hydrothermal reaction conditions. Recycling of the catalyst is challenging and significant amounts of sulfur leached out of the materials. Nevertheless, gas-phase sulfonation opens a path to tailored solid acids for application in various reactions. S-CTFs form the basis for multi-functional catalysts, containing basic coordination sites for metal catalysts, tunable structural parameters and surface acidity within one sole system.

“…At different metal loadings, varying particle sizes ranging from 2.7 to 5 nm were obtained with varying activity in the oxidation of CO. Low temperatures of 160 °C for full CO conversion were obtained for this active and stable catalyst. Recently, the aforementioned divinylbenzene‐based porous polymer derived by nanocasting of oxides was used as a convenient support for highly dispersed Pt nanoparticles 77. In the aerobic oxidation of ethanol and glycerol in an aqueous phase, they showed improved activity and selectivity compared to Pt supported on carbon‐ and alumina‐based catalysts.…”

The combination of the advantageous properties of molecular and solid catalysts is considered the “Holy Grail” in catalysis research. Great potential is provided by nanoporous polymers. Chemically well‐defined moieties in combination with a high stability render these materials suitable as catalyst supports for liquid‐phase and even aqueous‐phase catalytic processes, especially regarding the transition from fossil resources to renewable resources. In this Minireview, recent developments are summarized, covering the three main approaches: solid metal‐free organocatalysts, immobilized molecular catalyst species, and supported metal nanoparticles and clusters. Their potential is evaluated and the question as to whether nanoporous polymers can bridge the gap between homogeneous and heterogeneous catalysis is critically discussed.
