Nature has inspired scientists to develop green and sustainable nanomaterials with biomimetic functions. Particularly, biomimetic metallic nanostructures (biometal NPs) with unique optical, catalytic, and electrical properties have received tremendous attention in many fields, ranging from healthcare and agriculture to energy and environmental sciences. Biometal NPs synthesized by various natural resources such as plant extracts, biomolecules, bacteria, and even viruses possess unique biomimetic functions including but not limited to precise biorecognition, selfassembly, antibacterial/antiviral, and enzymatic properties. In this report, we first review the bioinspired synthesis of industrially important metal nanoparticles, followed by the discussion on how the different biological sources affect the biomimetic functions of the as-synthesized biometal NPs. Next, we review the recent advancement and applications of these biometal NPs in the fields of biomedical engineering and catalysis, which include the development of metallic nanobiosensors, biomedical imaging probes, nanotherapeutics (e.g., antimicrobial and photodynamic/photothermal therapeutic agents), as well as the design of multifunctional nanozymes and artificial metalloenzymes for chemical and biopharmaceutical industries. Finally, we highlight some of the latest advancements in nanobiomimicry and their emerging applications in clean energy, electronic devices, and data storage, which shows the game-changing role of biomimetic metallic nanostructures for various technological applications in the near future.

Ammonia is not only a vital source of fertilizers production, but also a hydrogen carrier with high energy density, which has the potential to replace the traditional fossil fuels. However, the industrial route for ammonia production (Haber-Bosch process) is a highly energy-intensive process owing to the harsh operating conditions requirement. It is important to develop a novel ammonia synthesis process with mild operating conditions. Chemical looping ammonia synthesis (CLAS) is known to be an innovative and environmentally-friendly low-pressure ammonia synthesis technology, which separates the overall ammonia synthesis reaction into nitrogen release and replenish reactions facilitated with a nitrogen carrier (NC). NC with high efficiencies is the key to the the practical feasibility of CLAS technology. In this work, the supported molybdenum-based NCs were prepared with ammonium molybdate, hexamethylenetramine, and ZSM-5 zeolites through a facile pyrolysis method at different temperatures, and the performance of N-release, N-fixation, and the cyclic CLAS of NCs were studied in detail. The results indicate that the supported molybdenum-based NC pyrolyzed at 450 ℃ outperformed other NCs with an average NH3 production rate of ca. 20000 μmol•g −1 •h −1 , which is two or three orders of magnitude higher than that of the known metal nitrides under similar conditions. Bulk and surface analyses of NCs indicated the migration of lattice nitrogen of NC during the direct hydrogenation step for NH3 formation. At N-fixation stage, the nitrogen vacancy of molybdenum-based NC is expected to be recharged from N2. However, the low kinetics is an important problem of NC nitridation. With the introduction of H2, the nitridation kinetics of NC was significantly enhanced, improving the NC regeneration. During a 12-cycle test at 600 ℃ and atmospheric pressure, and the ammonia production rate was stabilized at ca. 1500 μmol•g −1 •h −1 for each cycle. This article investigated the preliminary feasibility of the supported molybdenum-based nitride as NC during the process of CLAS and could provide a theoretical basis for the design and development of new types of NCs.

“…Over the past 7 years, the publications on nitrogen fixation have increased by nine times as shown in Figure 1a. Significant progress has also been made in exploring ammonia synthesis under mild conditions, [1,24,25] including the low-temperature thermal catalysis, [26] biochemical and biomimetic fixation, [27][28][29] plasma-induced catalysis, [30,31] electrocatalysis, [19,32,33] and photocatalytic fixation. [34][35][36][37] Among them, the photocatalytic N 2 reduction reaction (p-NRR) that using photocatalyst as medium to convert N 2 into ammonia under solar irradiation has attracted extensive attention with its publications rising by 90 times in just 7 years (Figure 1b).…”

Ammonia, the second most-produced chemical, is widely used in agricultural and industrial applications. However, traditional industrial ammonia production dominated by the Haber-Bosch process presents huge resource and environment issues due to the massive energy consumption and CO 2 emission. The newly emerged nitrogen fixation technology, photocatalytic N 2 reduction reaction (p-NRR), uses clean solar energy with zero-emission, holding great prospect to achieve sustainable ammonia synthesis. Although great efforts are made, the p-NRR catalysts still suffer from poor N 2 adsorption and activation, inferior light absorption, and fast recombination of photocarriers. Due to the tunable electronic structure of the metal-free polymeric graphitic carbon nitride (g-C 3 N 4 ), the above-mentioned issues can be significantly alleviated, making it the most promising p-NRR photocatalyst. This review summarizes the recent development of g-C 3 N 4 -based catalysts for p-NRR, including the working principle of p-NRR catalysts, the challenges of developing p-NRR catalysts, and corresponding solutions. Particularly, the roles of defect engineering and heterojunction construction on g-C 3 N 4 to the enhancement of photocatalytic performances are emphasized. In addition, computational studies are introduced to deepen the understanding of reaction pathways. At last, perspectives are provided on the development of p-NRR catalysts.
