Indirect photo-electrochemical detection of carbohydrates with Pt@g-C3N4 immobilised into a polymer of intrinsic microporosity (PIM-1) and attached to a palladium hydrogen capture membrane

Polymers of Intrinsic Microporosity in the Design of Electrochemical Multicomponent and Multiphase Interfaces

“…PIM-1 coatings were found to mechanically stabilize this particulate catalyst-electrode assembly and to help guide the hydrogen to the electrode surface. Similar results were reported in "indirect photoelectrochemical processes" 50 in which Pt@g-C 3 N 4 and PIM-1 were coated onto a thin palladium film. In this system, the production of hydrogen (in the presence of glucose, fructose, sucrose, or trehalose) occurs in a catalysis compartment independent of the electrochemical compartment.…”

Size‐Selective Photoelectrochemical Reactions in Microporous Environments: Clark Probe Investigation of Pt@g‐C3N4 Embedded into Intrinsically Microporous Polymer (PIM‐1)

“…Here, PIM‐1 is employed as a film over a deposit of Pt@g‐C 3 N 4 on the Teflon membrane of a commercial Clark‐type sensor (used here for detecting both O 2 and H 2 , see Figure 1). PIM‐1 films in conjunction with photocatalysts have been reported previously for Pt@TiO 2 [25] and for Pt@g‐C 3 N 4 on platinum surfaces [26] or on hydrogen‐permeable palladium membranes [27] . A key feature observed for PIM‐1 and similar polymers is the ability to affect gas reactivity in liquid (or triphasic) environments [28] .…”

“…sucrose) and reducing saccharides ( e. g . fructose) [27] . In order to better understand the role of the molecular quencher, here a comparison of five potential quenchers is investigated: sorbitol, gluconic acid, glucose, sucrose, and raffinose.…”

Effects of g-C3N4 Heterogenization into Intrinsically Microporous Polymers on the Photocatalytic Generation of Hydrogen Peroxide

“…Particulate g-C 3 N 4 can be employed as suspended particles 37 or 2D nanoparticles, 38 coated onto surfaces, 39 associated with other photocatalysts, 40 or embedded into polymers 41 or porous host materials. 42,43 It has been reported that g-C 3 N 4 in conjunction with graphene can be employed to photogenerate H 2 O 2 . 44 Defect engineering has been employed to increase rates of H 2 O 2 production.…”
