“…Shape memory polymers (SMPs), which can return from a temporary shape to the original shape in response to external stimuli, are a unique class of stimuli-responsive smart materials that is gaining increasing attention. − SMPs have many advantages compared with shape memory alloys and shape memory ceramics, including lightweight, adjustable transition temperatures, responsiveness to different stimuli, large deformations, and good biocompatibility. , These improved features mean that SMPs have a very wide range of potential applications in many fields, including medical equipment, self-healing materials, aerospace materials, soft robots, and flexible electronic materials. − The development of SMPs from petroleum-based raw materials, however, faces the same environmental problems as other uses of fossil resources and attention has turned to various low-cost and sustainable biomass resources as substitutes. − …”

The use of biomass raw materials as replacements for traditional fossil resources is becoming increasingly important, both to reduce pressure on nonrenewable resources and to reduce environmental pollution. The abundant natural polymer lignin is still not used effectively, and it would be a win–win strategy to develop lignin-based light-driven shape memory polymers, especially if the polymers could be recycled. In this work, recyclable lignin-based light-driven shape memory polymers (EELDs) that respond to heat and light were designed by combining the rigid structure of lignin with dynamic ester bonds. EELD31 (where 31 represents the mass ratio of enzymatic lignin epoxy resin to dithiodibutyric acid) had good overall mechanical properties and could be easily recycled, with 90.8% of the original tensile strength retained after recycling. The maximum tensile strength achieved with the EELDs was 45.2 MPa (EELD31), the maximum elongation at break exceeded 100% (EELD21), and the fracture energy was as high as 15.7 J cm–3 (EELD21). The EELDs also have good thermal stability and excellent shape memory properties. The shape fixation rate of EELD31 was as high as 99.0%, and the shape recovery rate was as high as 97.9%. Under 2 sun radiation, EELD31 showed a marked photothermal effect, reaching a temperature of 88 °C. Recycled EELD31 showed only a slightly reduced photothermal effect, reaching a temperature of 82 °C under the same conditions. EELD31 completed shape recovery in ∼85 s under 2 sun radiation. The excellent mechanical and light-driven shape memory properties of the EELDs, combined with their good recyclability, provide new ideas for the development and utilization of lignin-based light-driven shape memory polymers.

Among the feasible options for valorizing lignocellulosic biomass into value‐added products, biochar is considered to be extremely appealing and it could be applied easily in several established thermochemical processes. Biochar possesses a large surface area due to its porous nature, which permits easy use in various applications, including catalytic biofuel production. This work summarizes research on biochar generation processes, its critical physicochemical properties, and factors that influence them. Important studies adopting biochar catalysts for liquid biofuel production are critically reviewed, and the reaction mechanisms and biofuel yield are analyzed. Finally, challenges in the use of biochar‐based catalysts for biofuel production are presented, together with possible solutions. In general, this current work aims to provide the critical characteristics of biochar as a potential catalyst to biofuel synthesis toward sustainable bioenergy production.

“…Among the investigated technologies to convert biomass, [14][15][16][17] , gasication, i.e., the thermochemical conversion by partial oxidation at high temperatures of a solid carbonaceous feedstock to a gaseous product, is the most promising route for biomass valorization as it combines two main advantages: high exibility in terms of feedstock, and versatility to produce different energy carriers. The gaseous product from gasication, syngas, can be used as fuel gas for heat and electricity generation, and as a feedstock for the production of hydrogen, biofuels, and chemicals.…”
