Case Study

Highly Efficient Catalysts Prepared by Inserting Rhodium Ions and Rhodium Complexes into γ-Zirconium Hydrogenphosphate

Giannoccaro P, et al. Applied Catalysis A: General, 2005, 284(1-2), 77-83.

Monocyclic aromatic hydrocarbons can be effectively hydrogenated to corresponding aliphatic hydrocarbons by inserting rhodium (III) (Rh (III)) ions or Rh (III) complexes into γ-zirconium hydrogen phosphate [Zr(PO4)(H2PO4)] as ion exchange carriers. The obtained γ-Zr(PO4)2HxRhy and γ-Zr(PO4)2Hx(Rh-L)y catalysts have high activity and stability for benzene hydrogenation reaction.
Catalytic system and benzene hydrogenation reaction
· Under relatively mild condition (T = 393 K, pH2 = 1-4 MPa), The catalytic systems g-ZrP-Rh(III) and its N,N-diamine complex g-ZrP-Rh-L are prepared by intercalating rhodium(III) (Rh(III)) ions or Rh(III) N,N'-complexes (N, N' = 2,2'-bipyridine, 1,10-phenanthroline) into γ-titanium or zirconium hydrogen phosphate (γ-M(PO4)).
· Benzene hydrogenation: A total of 50 mg of g-ZrP-Rh0.15-2 H2O (equating to 2.24 × 10^2 mmol of Rh) was combined with 1.6 × 10^2 dm3 of benzene (180.2 mmol) in a 2 × 10^2 dm3 glass vial. This vial was placed inside a sealed 4.5 × 10^2 dm3 autoclave, which was then connected to a constant pressure hydrogen reservoir and pressurized to 2 MPa. The autoclave was positioned in an electric oven set to 393 K and allowed to react for 2 hours with stirring at 1000 rpm. Following the reaction period, the autoclave was cooled, and the reaction mixture was analyzed using GC and GC-MS to identify the reactants and products.

Zirconium(IV) Hydrogenphosphate as an Electrocatalytic Layer Additive for PEM Water Electrolysis

Zlotorowicz A, et al. International journal of hydrogen energy, 2015, 40(32), 9982-9988.

This work fabricated a composite electrocatalytic layer of iridium oxide, perfluorosulfonic acid ionomer, and zirconium hydrogen phosphate (ZrP) on a glassy carbon disk electrode, confirming that the addition of zirconium hydrogen phosphate to the electrocatalytic layer for proton exchange membrane (PEM) water electrolysis is ideal. The study showed that zirconium hydrogen phosphate was believed to be able to chelate excess phosphoric acid in the electrocatalytic layer, making it very suitable for incorporation into membranes that rely on phosphate-promoted proton conductivity.
Electrocatalytic layer preparation
Three electrocatalytic layers, each with a distinct structure, were constructed using synthesized iridium oxide, perfluorosulfonic acid ionomer, and commercial ZrP.
(a) A layer of iridium oxide combined with perfluorosulfonic acid ionomer was applied to a pre-treaded glassy carbon disk electrode and allowed to dry. Next, 5 mmol of ZrP powder was mixed with 1 mL of deionized water and combined with 1 mL of a diluted perfluorosulfonic acid ionomer solution in an ultrasonic bath for 15 minutes, after which it was applied atop the previously deposited oxide layer.
(b) Multiple aliquots (2 x 2) of ZrP suspended in perfluorosulfonic acid ionomer and iridium oxide in perfluorosulfonic acid ionomer were successively deposited onto the glassy carbon disk electrode and dried under a nitrogen gas stream between each application.
(c) ZrP, perfluorosulfonic acid ionomer, and iridium oxide powder were mixed together in an ultrasonic bath for 15 minutes before being applied to the disk electrode.
