Rationally designed ultrathin Ni(OH)2/titanate nanosheet heterostructure for photocatalytic CO2 reduction

Process coupling of CO2reduction and 5-HMF oxidation mediated by defect-enriched layered double hydroxides

“…[4][5][6] In this background, solardriven CO 2 reduction with H 2 O into high-value-added compounds, such as CO, CH 4 , C 2 H 6 , CH 3 OH, etc., via semiconductors is generally regarded as a promising technology for achieving the reduction of CO 2 emission and production of energy resources simultaneously. [7][8][9] However, the low efficiency of this process suffers from the slow kinetics rate of the water oxidation half-reaction (2H 2 O + 4h + /4H + + O 2 ), leading to the recombination of excited electrons and unused holes. [10][11][12] To minimize the issue, a common strategy is to employ sacrificial electron donors as hole scavengers.…”

Synthesis of Acrylate Dual-Tone Resists and the Effect of Their Molecular Weight on Lithography Performance and Mechanism: An Investigation

“…Lithography technology has played a critical role in the semiconductor industry [ 1 , 2 , 3 , 4 , 5 ], enabling the miniaturization of devices and the reduction in semiconductor nodes from 10 mm to 7 nm over the past 50 years [ 6 , 7 ]. Photoresist is one of the key materials for nanofabrication in lithography, and the patterning generated by lithography acts as an etch-resistant agent to protect the silicon substrate.…”

A novel bismuth hydroxide (Bi(OH)3) semiconductor with highly-efficient photocatalytic activity

“…Therefore, photocatalysts with abundant adsorption and activation sites and suitable energy band structure are required for highly-efficient reduction of CO 2 . 5 Hydroxides, such as In(OH) 3 , 6 Mg(OH) 2 7 and Ni(OH) 2 , 8 with excellent photocatalytic reduction of CO 2 , have recently been reported. It was found that the surrounding O-O bridges and hydroxyl group sites not only are good adsorbents for adsorbing acidic gas CO 2 , 9 but also can facilitate the oxidative removal of carbonaceous species, such as CO. 10 Moreover, abundant oxygen vacancies (OVs) caused by alkaline conditions during synthesis and the relatively high conduction band provide the necessary conditions for the CO 2 conversion reaction.…”
