“…Pd NPs were also deposited on Fe 2 O 3 modified AC to form a large surface area magnetic Pd/Fe 2 O 3 /AC catalyst. 42 The AC support was modified by Fe 2 O 3 ALD followed by Pd ALD. In hydrodechlorination of 1,4-dichlorobenzene the Fe 2 O 3 species in close contact with Pd effectively prevented the metal species from being poisoned by chloride ions and thus enhanced the catalytic performance.…”

“…(Martin-Martinez et al, 2016) Many studies have been performed on Pd-based HDC catalysts, among which Pd-Fe2O3 has been reported to be particularly effective. (Zhang et al, 2017) However, the ideal support for HDC reactions is a high surface area support. Thus, further improvement of the material resulted from impregnating Fe2O3 and Pd on the activated carbon, which earlier was reported as the best support candidate.…”

Supported bimetallic nanoparticulate catalysts are an important class of heterogeneous catalysts for many reactions including selective oxidation, hydrogenation/hydrogenolysis, reforming, biomass conversion reactions and many more. The activity, selectivity and stability of these catalysts depend on their structural features including particle size, composition and morphology. In this review, we present important structural features relevant to supported bimetallic catalysts focusing on Pd-based bimetallic systems and recently reported strategies to control them through different synthesis methodologies. Further, we focus on a few reactions that are relevant to environmental catalysis i.e. (a) CO oxidation, (b) hydrocarbon oxidation, (c) hydrodechlorination and (d) NOx decomposition where Pd-based catalysts are often used successfully. In spite of much progress in these areas, still there is a need for more advanced catalytic technologies to address the grand challenges like environmental remediation. Some of the recent advances in the design of bimetallic catalysts were made because of the combined efforts of material scientists, spectroscopists, microscopists, catalysis chemists and engineers through state-of-the-art characterisation methodologies, mechanistic investigations and structure-activity correlations. This review is aimed at inspiring scientists to rationally design catalysts for a green and sustainable future.

“…In the previous literature, two kinds of approaches have been applied to promote the dispersion of Pd nanoparticles. The first approach is the enhancement of interaction between Pd and supports by modification of supports or Pd precursors. , The second approach is the use of some special techniques such as supercritical sol–gel method and atomic layer deposition method. − Albeit interesting, it is time- and energy-consuming for the additional modification of supports/precursors and the utilization of special techniques. It is worth noting that Pd precursors are usually introduced to calcined SBA-15 ( CS ) conventionally, which is obtained from the calcination of as-made SBA-15 ( AS ) to remove the template.…”

Palladium (Pd)-containing catalysts have gained extensive attention because of their outstanding activity in various heterogeneous catalytic reactions. The activity of these catalysts highly correlates with the size of the Pd particles. Herein, nanosized Pd particles were fabricated by utilizing the as-made SBA-15 (AS) possessing nanoconfined spaces between the template P123 and silica walls. By using the inherent nanoconfined spaces in AS, Pd nanoparticles with a smaller size can be generated conveniently (yielding Pd-AS); in contrast, Pd is apt to aggregate and form larger-sized particles in the conventionally calcined SBA-15 (CS) without nanoconfined spaces (yielding Pd-CS). The smaller size of Pd nanoparticles in Pd-AS endows the catalysts with better catalytic activity in CO oxidation compared to their Pd-CS counterparts. On the typical sample 5Pd-AS with 5 wt % of Pd, the turnover frequency at 140 °C is 1.55 min −1 , which is superior to its analogue 5Pd-CS (0.22 min −1 ).
