“…Mesoporous carbon materials have gained paramount attention for applications in biomass conversion due to their controllable porous properties, therefore significantly differing from traditional carbon materials. [147][148][149] In addition, they exhibit high specific surface areas and tunable pore channels, fascinating interfacial features, unprecedented control over their morphology and a rich composition. Template-assisted carbonisation methods are widely used for the synthesis of mesoporous carbons as they provide an efficient control over pore arrangement, structure, and mesoporosity.…”

“…A combined catalytic and biotechnological process was developed for the production of HMF and bioethanol from cellulose. 149 In the first step, hydrolysis/dehydration of mechanically activated microcrystalline cellulose was carried out using a mesoporous carbon-based catalyst. Moderate yields of glucose and HMF were obtained.…”

Efficient transformation of biomass to value-added chemicals and high-energy density fuels is pivotal for a more sustainable economy and carbon-neutral society. In this framework, developing potential cascade chemical processes using functionalised heterogeneous catalysts is essential because of their versatile roles towards viable biomass valorisation. Advances in materials science and catalysis have provided several innovative strategies for the design of new appealing catalytic materials with well-defined structures and special characteristics. Promising catalytic materials that have paved the way for exciting scientific breakthroughs in biomass upgrading are carbon materials, metal-organic frameworks, solid phase ionic liquids, and magnetic iron oxides. These fascinating catalysts offer unique possibilities to accommodate adequate amounts of acid-base and redox functional species, hence enabling various biomass conversion reactions in a one-pot way. This review therefore aims to provide a comprehensive account of the most significant advances in the development of functionalised heterogeneous catalysts for efficient biomass upgrading. In addition, this review highlights important progress ensued in tailoring the immobilisation of desirable functional groups on particular sites of the above-listed materials, while critically discussing the role of consequent properties on cascade reactions as well as on other vital processes within the bio-refinery. Current challenges and future opportunities towards a rational design of novel functionalised heterogeneous catalysts for sustainable biomass valorisation are also emphasized.

“…Afterward, to liberate the fermentable sugars (i.e., monosaccharide units) from the pretreated biomass, acid or enzymatic hydrolysis processes are applied [ 14 ]. Then, the fermentation of the obtained sugars to obtain ethanol can be carried out using microorganisms as yeast or bacteria [ 15 , 16 ], where, in an integrated biorefinery, ethanol can also be considered as a precursor for chemicals, hydrocarbon fuels, and aromatic compounds [ 17 ]. Hence, the research and development of sustainable processes are growing not only for biofuels but also for the high added-value compounds than can allow an economically viable process ( Figure 1 ).…”

In Europe, pine forests are one of the most extended forests formations, making pine residues and by-products an important source of compounds with high industrial interest as well as for bioenergy production. Moreover, the valorization of lumber industry residues is desirable from a circular economy perspective. Different extraction methods and solvents have been used, resulting in extracts with different constituents and consequently with different bioactivities. Recently, emerging and green technologies as ultrasounds, microwaves, supercritical fluids, pressurized liquids, and electric fields have appeared as promising tools for bioactive compounds extraction in alignment with the Green Chemistry principles. Pine extracts have attracted the researchers’ attention because of the positive bioproperties, such as anti-inflammatory, antimicrobial, anti-neurodegenerative, antitumoral, cardioprotective, etc., and potential industrial applications as functional foods, food additives as preservatives, nutraceuticals, pharmaceuticals, and cosmetics. Phenolic compounds are responsible for many of these bioactivities. However, there is not much information in the literature about the individual phenolic compounds of extracts from the pine species. The present review is about the reutilization of residues and by-products from the pine species, using ecofriendly technologies to obtain added-value bioactive compounds for industrial applications.

“…Bioethanol is another biofuel product, which can be derived efficiently from crops and related cellulosic biomass. Porous nanomaterials have been explored as heterogeneous catalyst for the synthesis of bioethanol and 5‐HMF and this biotechnological approach is very promising for the conversion of biomass to bioenergy. Levulinate esters, another biofuel product can be synthesized by using supported mesoporous materials as catalyst from biomass derived levulinic acid .…”

In this personal account, several key inventions on designing novel microporous and mesoporous materials, and their applications in energy and environmental research are reviewed. Although, crystalline materials with sub-nanometer pore size regime like zeolites, AlPOs, MOFs, ZIFs etc. are known over the years, silicious and non-silicious mesoporous materials have revolutionized the research on the materials with nanoscale porosity in last two and half decades. A wide range of inorganic, organic-inorganic hybrid as well as purely organic mesoporous materials with either periodic or disordered mesopores are known. Apart from conventional hydrothermal syntheses involving soft templating route, hard templating, evaporation induced self-assembly (EISA), electrochemical or solvothermal (using hydrophilic solvents) synthetic routes are often employed in designing a large spectrum of mesoporous materials. Ease of synthesis using available cheap raw chemicals and versatility in the framework compositions together with the unique surface properties like exceptionally high surface area, pore volume and tunability in pore dimensions have made these materials very exciting to a wide range of researchers working on materials chemistry. Nanoscale porosity in the semiconductor nanomaterials is highly beneficial for the photocatalytic, optoelectronic and related light-harvesting applications. Their high chemical stability has been explored intensively in designing novel heterogeneous catalysts for the synthesis of biofuels from biomass or CO fixation to reactive organic molecules for the synthesis of fine chemicals and fuels, which has a large impact on energy and environmental research for the years to come. Diversity in mesoporous frameworks and their potential applications related to light harvesting, generation of renewable energy and synthesis of value added fine chemicals and fuels through environment friendly routes are mostly focused in this review.
