“…33 To solve this problem, doping N into the carbon matrix can effectively enhance the metal−support interactions to improve the stability of the attached metal catalyst. 34 The doped-N creates more active sites and binding sites to anchor more metal NPs on the carbon matrix, and adjusts the surface property of the carbon structures. The enlarged specific surface area also contributes to the interfacial electron transfer, eventually enhancing the catalytic characteristics.…”

As the raw material of polycarbonate and epoxy resins, bisphenol A (BPA) is widely employed in industrial production of commodities, such as plastic bottles and thermal paper. However, excessive amounts of BPA affect the immune system of the human body and damage the health. It is important to monitor BPA in environmental and industrial samples. Herein, a graphitic carbon-coated PtCoNi alloy supported on N-doped porous carbon nanoflakes (G-PtCoNi/N-PCFs) was successfully prepared by high-temperature pyrolysis. The characteristics (e.g., compositions and microstructure) of the G-PtCoNi/N-PCFs were characterized in detail, coupled by investigating the N-doping effect. Specifically, the well-dispersed PtCoNi alloy enhanced the catalytic activity, combined by inhibiting the poisoning effect of the species absorbed on the surface and improving the utilization of Pt with additional Co/Ni atoms. Moreover, the graphitic carbon shell further enhanced the catalytic stability of BPA. As a desirable electrode material, the G-PtCoNi/N-PCFs composite was applied for building an electrochemical sensor for the detection of BPA. Under optimal conditions, the resultant sensor exhibited outstanding catalytic activity and analytical performance with a wide linear range of 2.0−140.0 μM and a low limit of detection of 0.19 μM (S/N = 3), combined with the feasibility for detecting BPA in thermal paper and plastic bottles.

“…), with the aim of modifying the catalytic Pd NPs surface to achieve higher activities and selectivities [ 17 , 19 , 28 , 33 ]. Moreover, Pd-based NPs supported on N-doped carbon have proven to be excellent catalysts for several organic reactions [ 36 , 37 , 38 ]. On the other hand, Ru has mainly been used as a homogeneous catalyst [ 29 ] although interesting results for gas-phase FAD have been found while supported on metal and covalent organic framework (MOF and COF) materials [ 32 , 39 ].…”

Formic acid has recently been revealed to be an excellent hydrogen carrier, and interest in the development of efficient and selective catalysts towards its dehydrogenation has grown. This reaction has been widely explored using homogeneous catalysts; however, from a practical and scalable point of view, heterogeneous catalysts are usually preferred in industry. In this work, formic acid dehydrogenation reactions in both liquid- and vapor-phase conditions have been investigated using heterogeneous catalysts based on mono- or bimetallic Pd/Ru. In all of the explored conditions, the catalysts showed good catalytic activity and selectivity towards the dehydrogenation reaction, avoiding the formation of undesired CO.

Aniline is a group of important platform molecules that has been widely used in the synthesis of other high-value chemicals and pharmaceutical products. How to produce high-value anilines as the high-value chemical intermediates more efficiently and environmentally has always been a research topic in the industry. Catalytic hydrogenation is an environmentally friendly method for preparing halogenated anilines. Traditional noble metal catalysts face the problems of cost and noble metals residue. To improve the purity of the product as well as the activity and recyclability of the catalyst, we prepared a Pd/Fe magnetic bimetallic catalyst supported on N-doped carbon materials to reduce nitrobenzene to aniline under mild conditions. The catalyst has a low Pd loading of 2.35%. And the prepared bimetallic Pd/Fe@N/C catalyst showed excellent catalytic reactivity with the nitrobenzene conversion rate of 99%, and the aniline selectivity of 99% under mild reaction conditions of 0.8 MPa H 2 and 40 °C. A variety of halogenated and aliphatic nitro compounds were well tolerated and had been transformed to the corresponding target amine products with excellent selectivity. In addition, the novel N-doped graphene-encapsulated bimetallic magnetic Pd/Fe@N/C catalyst not only had magnetic physical properties, which was easy to separate, recover, and used for the recycling of the catalyst without metal leaching but also catalyzed highly selective reductive amination of aromatics was a green, economical and environmentally friendly reaction with the only by-product of H 2 O.
