“…It was found that the existing oxide layer has a negligible effect on the NORR activity of P−MoS 2 /NS ( Figure S2 ), which is consistent with the literature [42] . The peaks at 232.5 and 229.3 eV can be assigned to the Mo−P species [43] . The signals observed at 165.1 and 163.4 eV can be assigned to S 2 p 1/2 , and the peaks at 163.9 and 162.2 eV are indexed to S 2 p 3/2 ( Figure S3 ) [44,45] .…”

Ambient NH 3 electrosynthesis from NO reduction reaction (NORR) is attractive in replacing the industrial Haber-Bosch route; however, the competitive hydrogen evolution reaction (HER) in aqueous electrolyte typically induces a limited selectivity and activity toward NH 3 production. Herein, hierarchical P-doped MoS 2 nanospheres are developed as the NORR electrocatalyst in an ionic liquid (IL) electrolyte for catalyzing the reduction of NO to NH 3 with a maximal Faradaic efficiency of 69 % (À 0.6 V vs RHE) and a peak yield rate of 388.3 μg h À 1 mg cat.À 1 (À 0.7 V vs RHE), both of which are comparable to the best-reported results. Moreover, the catalyst also shows stable NORR activity over 30 h and 6 cycles. Theoretical analyses further reveal that the P dopants in MoS 2 facilitate the activation and hydrogenation of NO. Besides, the employment of hydrophobic IL electrolyte also slows down the HER kinetics effectively.

“…[ 77,78 ] The mycelia would provide the nutrition for the growth of conidia with different colors of white, yellow, and black. [ 52 ] Generally, the fermentation of Aspergillus spores mainly depends on the parasitic host with sufficient nutrition (e.g., cooked rice, [ 70,71 ] tofu, [ 72 ] steamed bran [ 67 ] ), PDA medium and liquid medium prepared by the potato, glucose, agar, and water. The culture conditions of the Aspergillus are similar and controlled at the temperature range of 25–37 °C, humidity of 60–70%, and natural pH value.…”

Biosynthesis methods are considered to be a promising technology for engineering new carbon‐based materials or redesigning the existing ones for specific purposes with the aid of synthetic biology. Lots of biosynthetic processes including metabolism, fermentation, biological mineralization, and gene editing have been adopted to prepare novel carbon‐based materials with exceptional properties that cannot be realized by traditional chemical methods, because microbes evolved to possess special abilities to modulate components/structure of materials. In this review, the recent development on carbon‐based materials prepared via different biosynthesis methods and various microbe factories (such as bacteria, yeasts, fungus, viruses, proteins) are systematically reviewed. The types of biotechniques and the corresponding mechanisms for the synthesis of carbon‐based materials are outlined. This review also focuses on the structural design and compositional engineering of carbon‐based nanostructures (e.g., metals, semiconductors, metal oxides, metal sulfides, phosphates, Mxenes) derived from biotechnology and their applications in electrochemical energy storage devices. Moreover, the relationship of the architecture–composition–electrochemical behavior and performance enhancement mechanism is also deeply discussed and analyzed. Finally, the development perspectives and challenges on the biosynthetic carbons are proposed and may pave a new avenue for rational design of advanced materials for the low‐carbon economy.

Potassium-ion batteries have emerged not only as low-cost alternatives to lithium-ion batteries, but also as high-voltage energy storage systems. However, their development is still encumbered by the scarcity of highperformance electrode materials that can endure successive potassium-ion uptake. Herein, a hydrated Bi-Ti bimetallic ethylene glycol (H-Bi-Ti-EG) compound is reported as a new high-capacity and stable anode material for potassium storage. H-Bi-Ti-EG possesses a long-range disordered layered framework, which helps to facilitate electrolyte ingress into the entire Bi nanoparticles. A suite of spectroscopic analyses reveals the in situ formation Bi nanoparticles within the organic polymer matrix, which can alleviate stresses caused by the huge volume expansion/contraction during deep cycles, thereby maintaining the superior structural integrity of H-Bi-Ti-EG organic anode. As expected, H-Bi-Ti-EG anode exhibits a high capacity and superior long-term cycling stability. Importantly for potassium storage, it can be cycled at current densities of 0.1, 0.5, 1, and 2 Ag −1 for 800, 700, 1000, and even 6000 cycles, retaining charging capacities of 361, 206, 185, and 85.8 mAh g −1 , respectively. The scalable synthetic method along with the outstanding electrochemical performance of hydrated Bi-Ti-EG, which is superior to other reported Bi-based anode materials, places it as a promising anode material for high-performance potassium storage.
