“…In early studies, noble metals like Ag and Pt were immobilized onto BC through physical mixing and subsequent free-drying or hydrothermal techniques. [108][109][110] Later, N-doped carbon nanofiber aerogels were obtained through a two-step pyrolysis successively in N 2 and NH 3 of the lyophilized BC, as shown in Figure 8a. [111,112] Except for getting nitrogen source from NH 3 gas, Ye et al reported a novel "vein-leaf" carbon structure through simple calcination of a mixture of urea and BC, in which urea acted as both the nitrogen source and the precursor for the layered graphitic carbon nitride (g-C 3 N 4 ).…”

Electrocatalysts used for oxygen reduction and oxygen evolution reactions are critical materials in many renewable‐energy devices, such as rechargeable metal–air batteries, regenerative fuel cells, and water‐splitting systems. Compared with conventional electrodes made from catalyst powders, oxygen electrodes with a freestanding architecture are highly desirable because of their binder‐free fabrication and effective elimination of catalyst agglomeration. Among all freestanding electrode structures that have been investigated so far, fibrous materials exhibit many unique advantages, such as a wide range of available fibers, low material and material‐processing costs, large specific surface area, highly porous structure, and simplicity of fiber functionalization. Recent advances in the use of fibrous structures for freestanding electrocatalytic oxygen electrodes are summarized, including electrospun nanofibers, bacterial cellulose, cellulose fibrous structures, carbon clothes/papers, metal nanowires, and metal meshes. After detailed discussion of common techniques for oxygen electrode evaluation, freestanding electrode fabrication, and their electrocatalytic performance, current challenges and future prospects are also presented for future development.

“…Bacterial cellulose (BC) synthesized by some microorganisms is beneficial for the energy and environmental sustainability. Advantages of the BC including ultrafine three-dimension networks, chemical stability, high crystallinity and excellent compatibility have triggered awareness focused on the catalytic application, such as support and template [9][10][11][12][13]. Mesoporous TiO 2 networks synthesized by BC membrane enhanced photocatalytic activity compared to TiO 2 networks templated by eggshell membranes [9].…”

Highly active CuO-CeO 2-ZrO 2 catalysts were prepared by sol-gel method, using environmentally friendly bacterial cellulose (BC) as structure directing regent. The catalyst designed with commercial BC (Com-BC) exhibited catalytic performances in toluene (T 100 =220 o C) and ethyl acetate oxidation (T 100 =170 o C) superior to the catalysts prepared by traditional methods. Furthermore, excellent stability was obtained and no deactivation was observed during the 100 h on stream in toluene and ethyl acetate oxidation at T 100. The excellent activity and stability of Com-BC can be explained by the hierarchically porous structure, abundant oxygen vacancies, and good reducibility.

Advanced Biomass‐Derived Electrocatalysts for the Oxygen Reduction Reaction

Recent progress in advanced nanostructures synthesized from biomass resources for the oxygen reduction reaction (ORR) is reviewed. The ORR plays a significant role in the performance of numerous energy-conversion devices, including low-temperature hydrogen and alcohol fuel cells, microbial fuel cells, as well as metal-air batteries. The viability of such fuel cells is strongly related to the cost of the electrodes, especially the cathodic ORR electrocatalyst. Hence, inexpensive and abundant plant and animal biomass have become attractive options to obtain electrocatalysts upon conversion into active carbon. Bioresource selection and processing criteria are discussed in light of their influence on the physicochemical properties of the ORR nanostructures. The resulting electrocatalytic activity and durability are introduced and compared to those from conventional Pt/C-based electrocatalysts. These ORR catalysts are also active for oxygen or hydrogen evolution reactions.
