“…As a result, the Co/Ni-CW shows an obviously enhanced water splitting performance with required overpotentials as low as 157 and 330 mV to achieve 10 mA cm -2 for HER and OER, respectively, which are comparable to the most reported Ni-, Co-, and Fe-based bifunctional electrocatalysts. [25][26][27][28][29][30][31] The great water splitting performances stem from the porous wood structure with uniformly distributed Co/Ni nanoparticles, which provided a tri-pathway for the efficient transport of electrons, ions, and gas (Figure 1c). More importantly, the Co/Ni-CW electrodes were used as cathode and anode for overall water splitting, leading to a cell voltage of 1.64 V to achieve 10 mA cm -2 with reasonable stability.…”

Using an inexpensive and eco-friendly wood substrate, herein, a one-step calcination method is developed to deposit Co-Ni binary nanoparticles into aligned wood channels and an effective carbonized wood (CW) electrode (termed as Co/Ni-CW) is fabricated. Well distributed Co-Ni nanoparticles are achieved by the coordination bonds between the hydroxyl groups on wood matrix and soaked metal cations. Subsequently, high-temperature calcination promotes the nucleation of Co-Ni nanoparticles and the formation of CW. With the uniform distribution of Co-Ni nanoparticles and porous wood structure, not only is a high active surface area, but also the electron and mass diffusion pathways are enhanced. Thus, the as-prepared Co/Ni-CW affords the current density of 10 mA cm -2 at low overpotentials of 330 and 157 mV for oxygen and hydrogen evolution, respectively. Remarkably, when the wood-based bifunctional electrocatalyst is used as both the anode and cathode, a low cell voltage of 1.64 V is required to reach the current density of 10 mA cm -2 . Compared with most substrates used in bifunctional electrocatalysts, the abundance, low cost, eco-friendliness, and easy operation of woodbased catalysts allow for an active and scalable electrode for water splitting and many other energy storage devices.

“…Carbon or graphene quantum dots have attracted intensive interest and have also been used to determine biomolecules due to their fascinating properties [ 145 , 146 , 147 , 148 ]. Doping heteroatoms (e.g., nitrogen, sulfur, phosphorus/or metal atoms) in carbon or graphene quantum dots is an effective way to tune their properties [ 107 , 112 , 149 , 150 ].…”

In recent years, sulfur-containing nanomaterials and their derivatives/composites have attracted much attention because of their important role in the field of biosensor, biolabeling, drug delivery and diagnostic imaging technology, which inspires us to compile this review. To focus on the relationships between advanced biomaterials and biosensors, this review describes the applications of various types of sulfur-containing nanomaterials in biosensors. We bring two types of sulfur-containing nanomaterials including metallic sulfide nanomaterials and sulfur-containing quantum dots, to discuss and summarize the possibility and application as biosensors based on the sulfur-containing nanomaterials. Finally, future perspective and challenges of biosensors based on sulfur-containing nanomaterials are briefly rendered.

A large number of researches on the electroless plating of carbon nanotubes and their applications after plating have emerged, which has attracted more and more attention. In this review article, the existing electroless plating methods for carbon nanotubes were briefly summarized, and the surface coatings were listed and analyzed in detail. At last, the related applications after electroless metal/alloy coatings of carbon nanotubes were discussed in detail. This study aims to provide a reference for the research and improvement of different electroless metals/alloys coatings of carbon nanotubes. After a clear understanding of the electroless metal/alloy coatings of carbon nanotubes, the appropriate coating can be selected according to the actual situation, so that the carbon nanotubes after plating can be used as reinforcement and modification materials for better satisfaction of the needs, and the application of plated carbon nanotubes has reference significance in more fields.
