pH universal Ru@N-doped carbon catalyst for efficient and fast hydrogen evolution

Abstract

<p>An efficient and robust hydrogen evolution electrocatalyst of Ru nanoparticles embedded in N-doped carbon was obtained by using Bu₄N[Ru(N)Cl₄] and Na₄EDTA as precursors. It exhibits excellent catalytic activity in alkaline solutions and good performance in acidic media.</p>

Highly Efficient Oxygen‐Modulated Ru‐Based HER Electrocatalyst in a Wide pH Range

“…As shown in Figure . 2a, the diffraction peaks corresponding to pure porous carbon and Ru can be ascribed to fullerene (JCPDS 81-2220) and metallic Ru (JCPDS 89-3942), respectively. [13] The peaks at 2θ = 38.39, 42. 19, 44.02, 58.35, 69.42, and 78.41°can be assigned to the (100), ( 002), ( 101), ( 102), (110), and (103) faces of Ru, respectively.…”

Hyperdispersed ruthenium nanoparticles anchored on S/N co-doped carbon nanotubes as an efficient HER electrocatalyst

“…The rest are assigned to the satellite peaks. 33,34 In order to compare the effects of heteroatom doping and supported ruthenium nanoparticles on the catalytic effect, we synthesized a series of materials. We tested a series of electrochemical properties of the materials to evaluate the catalytic performance of the HER.…”

Rational Design of Better Hydrogen Evolution Electrocatalysts for Water Splitting: A Review

“…Heteroatom doping directly and continuously fine‐tunes electronic structure and HER activity of the catalyst without changing the chemical composition. [ 183 , 184 , 185 , 186 , 187 , 188 , 189 , 190 , 191 , 192 , 193 , 194 , 195 ] Therefore, heteroatom doping is an effective strategy widely used to optimize HER activity. Transition metal doping (Fe, [ 196 ] Co, [ 197 , 198 ] Ni, [ 199 ] Zn, [ 200 ] and Mo [ 201 ] ) modifies the local electronic environment and can also optimize the interatomic distances and coordination numbers of active sites.…”
