Data for: Hydrogen production by photoelectrolysis

Published: 12 October 2021| Version 1 | DOI: 10.17632/rv5k5tbhsw.1


This dataset contains information regarding the patented methods (both application and granted patents) for the production of hydrogen by photoelectrolysis processes. The database used for data mining: Orbit Intelligence (a fee-based professional database provided by Questel), accessed on Oct. 9, 2021. The attached file contains information related to publication numbers, publication dates, title, abstract, current assignee, and claims. The patent search was carried out on the title (TI), abstract (AB), and claims (CLMS, ICLM) fields. Both IPC (International Patent Classification) and CPC (Cooperative Patent Classification) codes were used. The search strategy is reported in the following table: 1 707 (HYDROGEN OR "H_2")/CLMS/ICLM AND (C25B-001/55)/IPC/CPC 2 680 ((HYDROGEN 1W PRODUCTION))/CLMS/ICLM AND (B01J-035/004)/IPC/CPC 3 13 ( ((HYDROGEN 1W PRODUCTION))/TI/AB/CLMS/ICLM AND (PHOTO_ELECTROLYSIS)/DESC/ODES ) AND (H01L+)/IPC/CPC 4 1357 1 OR 2 OR 3 Definition of the classification codes used: C25B 1/55: Electrolytic production of inorganic compounds or non-metals • Processes •• Photoelectrolysis B01J 35/004: Catalysts, in general, characterized by their form of physical properties • Catalysts characterized by their physical properties •• Photocatalysts H01L: Semiconductor devices
