AB  - Artificial leaves (a-leaves) can reduce carbon dioxide into syngas using solar power and could be combined with thermo- and biocatalytic  technologies  to  decentralize  the  production  of  valuable  products.  By  providing  variable  CO:H2  ratios  on  demand,  a-leaves  could  facilitate  optimal  combinations  and  control  the  distribution  of  products  in  most  of  these  hybrid  systems.  However,  the  current  design   procedures   of   a-leaves   concentrate   on   achieving   high   performance  for  a  predetermined  syngas  composition.  This  study  demonstrates  that  incorporating  the  electrolyte  flow  as  a  design  variable     enables     flexible     production     without     compromising     performance.   The   concept   was   tested   on   an   a-leaf   using   a   commercial  cell,  a  Cu2O:Inx  cathodic  catalyst,  and  an  inexpensive  amorphous silicon thin-film photovoltaic module. Syngas with CO:H2ratio in the range of 1.8-2.3 could be attained with only 2% deviation from the optimal cell voltage and controllable solely by catholyte flow. These  features  could  be  beneficial  for  downstream  technologies  such as Fischer Tropsch synthesis and anaerobic fermentation.
