Modular Layer‐by‐Layer Assembly of Polyelectrolytes, Nanoparticles, and Molecular Catalysts into Solar‐to‐Chemical Energy Conversion Devices

Abstract: The design and fabrication of solar-to-chemical energy conversion devices are enabled through interweaving multiple components with various morphologies and unique functions using a versatile layer-by-layer assembly method. Cationic and anionic polyelectrolytes are used as an electrostatic adhesive to assemble the following functional materials: plasmonic Ag nanoparticles for improved light harvesting, upconversion nanoparticles for utilization of nearinfrared light, and polyoxometalate water oxidation catalys… Show more

“…The modulation of the charge separation efficiency of photoelectrodes with polyelectrolyte‐assembled interfacial dipole layers is schematically depicted in Scheme . LbL assembly is particularly well suited for formation of interfacial dipole layers, as it enables the assembly of polyelectrolyte multilayers at a nanometer‐scale precision regardless of electrode structures without altering the bulk properties of photoelectrodes . Thus, the bulk properties of photoelectrodes, such as bandgap and conductivity, remain intact while their interfacial properties could be engineered.…”

“…LbL assembly is particularly well suited for formation of interfacial dipole layers, as it enables the assembly of polyelectrolyte multilayers at a nanometer-scale precision regardless of electrode structures without altering the bulk properties of photoelectrodes. [37,38] Thus, the bulk properties of photoelectrodes, such as bandgap and conductivity, remain intact while their interfacial properties could be engineered. In this study, PDDA and PSS were selected as the cationic and anionic polyelectrolytes for modifying photoanodes, owing to the following characteristics: i) high electrochemical stability (Figure S1, Supporting Information), ii) distinct charge density independent of external pH as strong electrolytes, and thereby, and iii) formation of stable polyelectrolyte multilayers on various photoanodes, which have different stability and/or operating pH windows.…”

“…Layer-by-Layer (LbL) assembly has been established as a simple, green, and labor-saving method to construct multilayer nanostructures with customized architectures in terms of universality, versatility, and multi-functionality. [32][33][34] The interface conguration of LbL assembled nano-architectures can be readily tailored via mediating the assembly cycle and sequence. Enlightened by the negatively charged surface of metal NCs, we infer that metal NCs can be selected as building blocks and alternately stacked on metal oxide (MO) substrates with the oppositely charged non-conjugated insulating polymer via electrostatic interaction, resulting in the spatially multilayered MO-(metal NCs/polymer) n heterostructures.…”
