Welcome and apology
[edit]I removed your recent contribution to Catalysis. For a topic so large as catalysis, we really need ver ygeneral sourcing. To put the situation in perspective, Chemical Abstracts has abstracted 454586 articles, patents, etc on "catalysis", 17,351 in 2019 alone, i.e. about 100 papers per day. Citations are a strength of Wikipedia but they need to be rather general for big topics. Sorry to greet you in this way, and I hope that you will continue to contribute. Many editors can offer advice.--Smokefoot (talk) 13:26, 7 October 2019 (UTC)
