Catalytic activity of aluminium-rich hematite in the water gas shift reaction

Iron-Based Catalysts for the High-Temperature Water–Gas Shift (HT-WGS) Reaction: A Review

“…The iron catalyst containing Al 2 O 3 and CeO 2 showed sufficient thermal resistance and the highest activity that was claimed to be superior in activity to a commercial HT-WGS catalyst. Most of the reported findings were trial-and-error studies and only discussed the activity and thermal-stability under different reaction conditions. ,,,− Araujo and Rangel synthesized Fe–Al, Fe–Cu, and Fe–Al–Cu catalysts by coprecipitation and claimed the Fe–Al–Cu catalyst has similar HT-WGS activity compared to a commercial Cr-containing catalyst. Liu et al synthesized Fe–Al–Ce catalysts by wet precipitation that exhibited high activity and thermal-stability even after pretreatment at 530 °C, which was claimed to be comparable to those of commercial Cr–Fe catalysts.…”

Simulations for charge transfer and photocurrent calculations using hematite for green hydrogen production

“…Hematite is one of the most widely-studied materials as a catalyst for both processes. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] However, it has some drawbacks, including short hole diffusion lengths, high recombination, bad surface chemistry, 21 and poor thermodynamics. 9 Several works studied photocurrent obtained through hematite, 22,23 both by experiments and by theoretical studies, using various simulations.…”

Synthesis of a high dielectric constant graphene supported iron oxide and its electrocatalytic activity in a H2O2 fuel cell and as an efficient photocatalyst

“…2 Among all these, hematite is considered to be of prime importance in terms of its application in the areas of catalysis, photocatalysis, electrochemistry and biomedicines. 3–7 Hematite is studied for its photocatalytic activity in the visible region due to its band gap of 2.1 eV and it is also considered to be an excellent candidate for the water splitting process. 8,9 In the case of microbial fuel cells (MFC) different electron acceptors are being studied wherein they receive electrons from the cathode and therefore make a significant contribution to performance of the MFC.…”
