“…It can thus be concluded that, a catalyst is required for the reduction to take place and PSf can be a good support for entrapment of the catalytic PdNPs. Similar observations have been reported elsewhere [44].…”

Enhancing the catalytic activity of supported nanocatalysts is an effective strategy to mitigate costly catalyst separation processes in many industrial processes. In this study, catalytic polysulfone (PS) membranes decorated with in-situ synthesized palladium nanoparticles (PdNPs) were fabricated. The membranes were characterised by SEM, XRD, SAXSpace, FTIR, TEM, AFM, contact angle measurements and EDS. Effect of different amounts of PdNPs on the physicochemical properties, water flux, contact angle and catalytic activity for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) were investigated, and the degradation mechanism proposed. Results showed a uniform dispersion of small (~5 nm) PdNPs in the membrane. Water flux correlated well with increased membrane porosity which was a function of PdNP loading within the membranes. The Pd loaded membranes showed improved hydrophilicity. Very low PdNP loading (1.0 wt %) resulted in about 90% reduction of 4-NP to 4-AP was mainly due to the catalytic effect of PdNPs.

“…Extensive research efforts have been devoted to develop active and selective solid catalyst materials with bifunctional natures for both H 2 generation and hydrogenolysis reactions. Pt-based ( Tike and Mahajani, 2006 ; Falcone et al, 2015 ; Feng et al, 2015 ; Von Held Soares et al, 2017 ; Zhang et al, 2020b ; Hu et al, 2020 ; Xia et al, 2020 ; Nie et al, 2021 ; Song et al, 2021 ), Cu-based ( Nie et al, 2021 ; Feng et al, 2015 ; Wang et al, 2015b ; Priya et al, 2016 ; Feng et al, 2011 ; Kant et al, 2017 ; Vasiliadou and Lemonidou, 2013 ; A et al, 2017 ), and Pd-based ( Tike and Mahajani, 2006 ; Feng et al, 2015 ; Mauriello et al, 2015 ; Sun et al, 2017 ; Shafaghat et al, 2019 ; Xia et al, 2020 ; Song et al, 2021 ) catalysts have been proposed and investigated with respect to structure-performance relations. Those studies have confirmed that CTH of glycerol can be achieved under milder temperatures (<200 o C) and pressures (inert <2 MPa), with remarkable atom efficiency for the synthesis of PG as the main product ( Wang et al, 2013 ; Feng et al, 2015 ).…”

Hydrogenolysis of glycerol to propylene glycol represents one of the most promising technologies for biomass conversion to chemicals. However, conventional hydrogenolysis processes are often carried out under harsh H2 pressures and temperatures, leading to intensive energy demands, fast catalyst deactivation, and potential safety risks during H2 handling. Catalytic transfer hydrogenolysis (CTH) displays high energy and atom efficiency. We have studied a series novel solid catalysts for CTH of glycerol. In this work, detailed studies have been conducted on energy optimization, tech-economic analysis, and environmental impact for both processes. The key finding is that relatively less energy demands and capital investment are required for CTH process. CO2 emission per production of propylene glycol is much lower in the case of transfer hydrogenolysis. The outcome of this study could provide useful information for process design and implementation of novel hydrogenolysis technologies for other energy and environmental applications.

“…[40][41][42] On the other hand, AB has been also used as hydrogen source in the transfer hydrogen reactions in recent years. [43][44][45][46] However, the cost of AB (20 euro g À1 ) 47 is too high for the practical applications. In this regard, in our recent work, we have publicized morpholine borane (MB) as a new, safe, and cheap hydrogen storage material for the first time.…”
