“…Some inorganic nanoparticles have ability to act as reducing agent to convert Cr(VI) to Cr(III). Zerovalent iron ( Zhao et al, 2020 ), iron sulfide ( Yu et al, 2020 ), iron oxide ( Yi et al, 2020 ) and iron based bimetallic ( Ruan et al, 2020 ) nanoparticles have been reported as reducing agents for reduction of Cr(VI) to Cr(III). Iron exists in low oxidation state in such kind of nanoparticles and is oxidized simultaneously during Cr(VI) reduction.…”

“…Therefore, they are fabricated in the presence of a stabilizing system. Synthesis of FeS nanoparticles in the presence of various stabilizing agents has been widely reported in recent literature but general synthetic scheme is almost similar and has been described here ( Wang et al, 2019 ; Yu et al, 2020 ; Lyu et al, 2017 ; Wu et al, 2017 ; Li et al, 2017 ; Wang et al, 2011 ; Tan et al, 2020 ). For example, Li et al (2017) have reported synthesis of FeS nanoparticles using carboxymethyl cellulose (CMC) as stabilizer in aqueous medium by displacement reaction between FeSO 4 .7H 2 O and Na 2 S in aqueous medium under N 2 atmosphere.…”

“…Over the past few years, significant research has been conducted to identify the effect of nanoparticle size on catalytic performance for various chemical transformations [16]. As the particle size decreases, their surface area-to-volume ratio is enhanced, allowing more atoms on the surface to take part in the reaction [17]. As a result, improved catalyst activity and selectivity can be achieved.…”

Nanocatalysis is an emerging field of research and is applicable to nearly all kinds of catalytic organic conversions. Nanotechnology is playing an important role in both industrial applications and academic research. The catalytic activities become pronounced as the size of the catalyst reduces and the surface area-to-volume ratio increases which ultimately enhance the activity and selectivity of nanocatalysts. Similarly, the morphology of the particles also has a great impact on the activity and selectivity of nanocatalysts. Moreover, the electronic properties and geometric structure of nanocatalysts can be affected by polar and nonpolar solvents. Various forms of nanocatalysts have been reported including supported nanocatalysts, Schiff-based nanocatalysts, graphene-based nanocatalysts, thin-film nanocatalysts, mixed metal oxide nanocatalysts, magnetic nanocatalysts, and core-shell nanocatalysts. Among a variety of different rare earth and transition metals, palladium-based nanocatalysts have been extensively studied both in academia and in the industry because of their applications such as in carbon-carbon cross-coupling reactions, carbon-carbon homocoupling reactions, carbon-heteroatom cross-coupling reactions, and C-H activation, hydrogenation, esterification, oxidation, and reduction. The current review highlights the recent developments in the synthesis of palladium and some other metal nanocatalysts and their potential applications in various organic reactions.

“…A CF electrode (1 × 2 × 0.5 cm) was used as the anodic electrode 61 . M9 salt medium with Wolfe mineral and Wolfe vitamin was used as the anode medium 62 , and sodium lactate (18 mM) was supplemented as the sole carbon source. Native SW cells or SW@S cells were suspended in the anode medium to an OD 600 = 1.0, and purged with nitrogen gas for 30 min to remove the dissolved oxygen.…”

By electronically wiring-up living cells with abiotic conductive surfaces, bioelectrochemical systems (BES) harvest energy and synthesize electric-/solar-chemicals with unmatched thermodynamic efficiency. However, the establishment of an efficient electronic interface between living cells and abiotic surfaces is hindered due to the requirement of extremely close contact and high interfacial area, which is quite challenging for cell and material engineering. Herein, we propose a new concept of a single cell electron collector, which is insitu built with an interconnected intact conductive layer on and cross the individual cell membrane. The single cell electron collector forms intimate contact with the cellular electron transfer machinery and maximizes the interfacial area, achieving record-high interfacial electron transfer efficiency and BES performance. Thus, this single cell electron collector provides a superior tool to wire living cells with abiotic surfaces at the single-cell level and adds new dimensions for abiotic/biotic interface engineering.
