{Based on|According to|Depending on|Determined by} H-cell measurements, gold (Au) {is one of the|is among the|is amongst the} most selective catalysts for the CO2 reduction reaction (CO2RR) to CO. {To ensure|To make sure} a {high|higher} dispersion, {typically|usually|normally|generally|commonly|ordinarily} Au {small|little|tiny|modest|smaller|compact} nanoparticles (NPs) are {used|utilized|employed|utilised|applied|made use of} as catalyst. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, the preparation of {small|little|tiny|modest|smaller|compact} Au NPs {based on|according to|depending on|determined by} {conventional|standard|traditional} synthesis {methods|techniques|strategies|approaches|procedures|solutions} {often|frequently|usually|typically|generally|normally} {requires|demands|needs|calls for} {the use of|the usage of} surfactants {such as|like|including|for example|for instance|which include} polyvinylpyrrolidone (PVP). {Here|Right here}, we present a systematic evaluation {of the|from the|in the|on the|with the|of your} {performance|overall performance|efficiency|functionality} of laser-generated, surfactant-free Au NPs for the CO2RR {in a|inside a|within a} gas diffusion electrode (GDE) setup and {compare|evaluate|examine} {the results|the outcomes} to investigations in an H-cell configuration. The GDE setup supplies a continuous CO2 stream {at the|in the} electrode−electrolyte interface to circumvent CO2 mass transport limitations encountered in {conventional|standard|traditional} H-cells. We investigate the influence {of the|from the|in the|on the|with the|of your} catalyst loading {and the|and also the|as well as the|along with the|plus the} {effect|impact} of PVP. Comparing the two screening {methods|techniques|strategies|approaches|procedures|solutions}, i.e. GDE and H-cell measurements, {it is|it’s|it really is|it truly is|it can be|it is actually} shown that the {performance|overall performance|efficiency|functionality} {of the|from the|in the|on the|with the|of your} {same|exact same|identical|very same|similar} catalyst {can be|may be|could be|might be|is often|is usually} substantially {different|various|distinct|diverse|unique|distinctive} {in the|within the|inside the} two environments. {In the|Within the|Inside the} GDE setup {without|with out|without having|with no|devoid of|without the need of} liquid electrolyte-catalyst interface a {higher|greater|larger} reaction {rate|price}, but {lower|reduce|reduced|decrease} faradaic efficiendy is determined. Independent {of the|from the|in the|on the|with the|of your} setup, the presence of PVP favours the hydrogen evolution reaction (HER), {however|nevertheless|nonetheless|even so|on the other hand|having said that}, {in the|within the|inside the} GDE setup PVP is {more|much more|a lot more|far more|additional|extra} detrimental for the {performance|overall performance|efficiency|functionality} than {in the|within the|inside the} H-cell.
