Ultrasonic-assisted hydrothermal synthesis of RhCu alloy nanospheres for electrocatalytic urea production

Abstract

Herein, the electronic structure of RhCu nanospheres was optimized and the size of the nanoparticles was reduced by an ultrasonic-assisted hydrothermal method. The performance of electrocatalytic urea synthesis was improved,...

Mild and scalable synthesis of a high performance CrFeCoNiRu0.05 high entropy nano-alloy/carbon electrocatalyst for efficient urea production with a chelate-based ionic liquid

“…5 –HENA/C catalysis. 34 The peak at 3654 cm −1 could be assigned to the distinct OH signal, verifying the existence of HOCONH 2 after the hydrogenation reaction. Then, HOCONH 2 loses –OH to produce CONH 2 , which is a reactant in the 2nd C–N coupling.…”

Ultrasound‐Assisted Preparation and Performance Regulation of Electrocatalytic Materials

“…The ultrasonic-hydrothermal method combines ultrasound technology with a hydrothermal method, which proves to be an effective method for synthesizing electrocatalysts. [91][92][93] Compared with the traditional hydrothermal method, the ultrasonic hydrothermal method can produce electrocatalysts with small particle size, large specific surface area, high pore volume, improved catalytic activity, high catalytic efficiency, and significantly shortened catalytic time. Therefore, the ultrasonic hydrothermal method combining ultrasonic and traditional hydrothermal methods is very essential.…”

Single-atom Cu anchored on Mo2C boosts nitrite electroreduction to ammonia

“…24 Among them, Cu-SACs have been demonstrated to be active and selective towards the N-cycle electrocatalysis reactions where ammonia is the main reductive product. [25][26][27][28][29][30] In addition, transition metal carbides such as Mo 2 C represent appealing SAC platforms because Mo 2 C not only possesses a high conductivity to favor rapid electrocatalytic kinetics, but also exhibits abundant surface-exposed Mo sites which may cooperate with singleatomic metal sites to synergistically promote the catalytic activity. [31][32][33] As illustrated in Fig.…”
