“…[19][20][21][22] Hence, it is vital to search for low-cost and highly active electrocatalysts as substitute materials for these noble metal-based catalysts. For example, lots of transition metal oxides, 23,24 suldes, 25,26 nitrides, 27,28 phosphides 29,30 and alloys 31,32 have been developed as low-cost and durable electrocatalysts. Exploring more effective catalysts for overall water splitting is always a prosperous topic in electrochemical water splitting.…”

“…UV‐vis DRS spectra were conducted to study the influence of Al 2 O 3 coating layers on the light harvesting ability of FeVO 4 . In Figure 4, FeVO 4 shows a typical absorption of semiconductor solid, and its bandgap energy was calculated to be 2.17 eV according to the Tauc plot [10d] . For FeVO 4 @Al 2 O 3 ‐x, no significant change in optical properties was disclosed, since the Al 2 O 3 layer with a bandgap energy of 3.94 eV is colorless and transparent [17] .…”

Improved Durability and Activity of FeVO₄ toward Photocatalytic Benzene Hydroxylation by Atomic Layer Deposited Al₂O₃

Selective hydroxylation of benzene to phenol over a visible light driven photocatalyst is a sustainable approach for the green synthesis of phenol. Iron vanadate (FeVO4) nanorods with an intrinsic photo‐Fenton catalytic behavior toward H2O2 activation is a promising candidate photocatalyst for the benzene hydroxylation reaction; however, its photocatalytic performance was greatly limited by the serious leaching of metals during the hydroxylation process. Herein, it has been demonstrated that this issue can be well addressed by the conformably coating of FeVO4 nanorods with an atomically‐precise thickness controlled dense Al2O3 layer (FeVO4@Al2O3) through the atomic layer deposition (ALD) technology. The Al2O3 nanolayer can well protect the FeVO4 nanorods from directly contacting with the reaction solution, thus effectively suppressing the leaching of metals during the photocatalytic hydroxylation process. In addition, the Al2O3 coating on FeVO4 also facilitates the kinetic control of heterogeneous benzene hydroxylation reaction over the catalyst surface, such as the benzene adsorption behavior and the photo‐Fenton activation of H2O2. As a result, FeVO4@Al2O3 exhibited an enhanced photocatalytic performance with a good durability in the long‐term production of phenol.

Ni, Fe, and Cu foams to form robust binder-free electrodes for high-performance electrocatalytic reactions. [55][56][57][58][59] Interestingly, multidimensional electrocatalysts grown at the nanoscale on a range of current collectors, namely substrates and will benefit from a strong adhesion with the current collector to avoid catalyst delamination, limited active sites, and charge transfer blockage to enhance catalytic reactions (Figure 1b-d). [9,[60][61][62][63][64] Key Prospects, Insights, and the Dynamic Properties of Nano-and Microstructured Binder-Free Electrocatalysts and Their Direct Impact on Electrochemical ReactionsWater splitting has become one of the most important technologies to produce hydrogen (H 2 ) in high purity form. Water splitting includes two half-reactions, namely the cathodic HER and anodic OER. [8,65] Generally, the electrocatalytic performance and activity are highly sensitive to local reaction conditions and is largely valued by the energy required for adsorption/desorption of reaction intermediates and the rupture/creation of chemical bonds. Hence, the conventional powder form of precious metals such as Pt/C for the HER and RuO 2 or IrO 2 for the OER are considered ideal electrocatalysts. [66] In addition, several nonprecious 1D, 2D, and 3D nano-and microstructured powder catalysts such as MoS 2 , WS 2 , Ni 3 S 2 , NiCo 2 S 4 are also of interest for the HER and OER reactions. [54,[67][68][69][70][71][72][73][74] However, for commercial purposes and practical applica-
